[MOAB-dev] pytaps: can't import iBase and iMesh

[Anthony Scopatz]

Hello Huayi,

This means that you have not linked iMesh.so to MOAB.  This is also what "U
imesh_getentities_" means (the U stands for undefined). There probably was
an error thrown in the setup.py.  Can you please report the full output of
a clean build?  Thanks!

Be Well
Anthony
