I am trying to get openbabel to compile on Mac OS X because I need the Python bindings. In general, I can get most of openbabel with python bindings working using the instructions I have written in this page: http://pythonhosted.org/pymatgen/installation.html#installation-tips-for-optional-libraries. Pls note that I have since upgraded to openbabel 2.3.2 and eigen3.
However, it seems that eigen3 is not detected at all. When I do
import openbabel as ob
I get an AttributeError. Switching back to eigen2 did not work either.
Can someone advise on how to get openbabel with python working properly on a Mac? I would also suggest making those instructions available somewhere.
