Thanks. I have now reached the point where I need test the PyOP2 installation, but when I write make test I get an error which I believe is related to open-mpi. It looks like libpetsc references the path /private/tmp/pip-hBwvhb-build/macosx-10.9-x86_64-python/lib/libhwloc.5.dylib which seems strange to me. The error log is: cd test; py.test unit --backend=sequential Traceback (most recent call last): File "/usr/local/lib/python2.7/site-packages/_pytest/config.py", line 543, in importconftest mod = conftestpath.pyimport() File "/usr/local/lib/python2.7/site-packages/py/_path/local.py", line 641, in pyimport __import__(modname) File "/Users/matak/PyOP2/test/conftest.py", line 40, in <module> from pyop2 import op2 File "/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PyOP2-0.11.0_124_ge15b3ee-py2.7-macosx-10.9-x86_64.egg/pyop2/__init__.py", line 9, in <module> from op2 import * File "/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PyOP2-0.11.0_124_ge15b3ee-py2.7-macosx-10.9-x86_64.egg/pyop2/op2.py", line 39, in <module> import base File "/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PyOP2-0.11.0_124_ge15b3ee-py2.7-macosx-10.9-x86_64.egg/pyop2/base.py", line 54, in <module> from sparsity import build_sparsity ImportError: dlopen(/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PyOP2-0.11.0_124_ge15b3ee-py2.7-macosx-10.9-x86_64.egg/pyop2/sparsity.so, 2): Library not loaded: /private/tmp/pip-hBwvhb-build/macosx-10.9-x86_64-python/lib/libhwloc.5.dylib Referenced from: /usr/local/lib/python2.7/site-packages/petsc/lib/libpetsc.3.05.2.dylib Reason: image not found ERROR: could not load /Users/matak/PyOP2/test/conftest.py make: *** [unit_sequential] Error 4 Thank you.
