I have troubles installing pygraphviz on macOS 10.10.5. I have a fully functional installation of Python 2.7.x, and I'd like to run the test example of queueing-tool, which requires installing pygraphviz using pip. When executing the command pip install pygraphviz, I get the following lengthy error message: Collecting pygraphviz Using cached pygraphviz-1.3.1.zip Building wheels for collected packages: pygraphviz Running setup.py bdist_wheel for pygraphviz ... error Complete output from command /usr/local/opt/python/bin/python2.7 -u -c "import setuptools, tokenize;__file__='/private/var/folders/x3/nr48r8q10dv1lb9l9t_yx7kh0000gq/T/pip-build-Ljj4Ox/pygraphviz/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" bdist_wheel -d /var/folders/x3/nr48r8q10dv1lb9l9t_yx7kh0000gq/T/tmpcYcoACpip-wheel- --python-tag cp27: running bdist_wheel running build running build_py creating build creating build/lib.macosx-10.10-x86_64-2.7 creating build/lib.macosx-10.10-x86_64-2.7/pygraphviz copying pygraphviz/__init__.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz copying pygraphviz/agraph.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz copying pygraphviz/graphviz.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz copying pygraphviz/release.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz copying pygraphviz/version.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz creating build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/__init__.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_attribute_defaults.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_attributes.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_clear.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_drawing.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_edge_attributes.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_graph.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_html.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_layout.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_node_attributes.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_readwrite.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_string.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_subgraph.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests copying pygraphviz/tests/test_unicode.py -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz/tests running egg_info writing pygraphviz.egg-info/PKG-INFO writing top-level names to pygraphviz.egg-info/top_level.txt writing dependency_links to pygraphviz.egg-info/dependency_links.txt warning: manifest_maker: standard file '-c' not found reading manifest file 'pygraphviz.egg-info/SOURCES.txt' reading manifest template 'MANIFEST.in' warning: no previously-included files matching '*~' found anywhere in distribution warning: no previously-included files matching '*.pyc' found anywhere in distribution warning: no previously-included files matching '.svn' found anywhere in distribution no previously-included directories found matching 'doc/build' writing manifest file 'pygraphviz.egg-info/SOURCES.txt' copying pygraphviz/graphviz.i -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz copying pygraphviz/graphviz_wrap.c -> build/lib.macosx-10.10-x86_64-2.7/pygraphviz running build_ext building 'pygraphviz._graphviz' extension creating build/temp.macosx-10.10-x86_64-2.7 creating build/temp.macosx-10.10-x86_64-2.7/pygraphviz clang -fno-strict-aliasing -fno-common -dynamic -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/usr/local/include -I/usr/local/opt/openssl/include -I/usr/local/opt/sqlite/include -I/usr/local/Cellar/python/2.7.12_2/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c pygraphviz/graphviz_wrap.c -o build/temp.macosx-10.10-x86_64-2.7/pygraphviz/graphviz_wrap.o pygraphviz/graphviz_wrap.c:3321:12: warning: incompatible pointer to integer conversion returning 'Agsym_t *' (aka 'struct Agsym_s *') from a function with result type 'int' [-Wint-conversion] return agattr(g, kind, name, val);
