Thanks for your reply.  I took your advice, and I found out that it
successfully compiled if I installed the Ubuntu packages
"libmeep-mpi-default-dev" and "meep-mpi-default", and then changed the
extension in the setup-mpi.py to "_meep_mpi-default" and the libraries var
to "meep_mpi-default".

So it successfully compiled, but when I tried to execute an mpi script, it
gives me this error:

*username@ubuntu:~/python-meep-1.4.2/python-meep/samples$ mpipython
./python_meep_symmetry_straight_wg.py*
*Traceback (most recent call last):*
*  File "./python_meep_symmetry_straight_wg.py", line 7, in <module>*
*    from meep_mpi import *  # make it 'meep_mpi' for MPI-meep and 'meep'

*  File "/usr/local/lib/python2.7/dist-packages/meep_mpi.py", line 26, in
<module>*
*    _meep_mpi = swig_import_helper()*
*  File "/usr/local/lib/python2.7/dist-packages/meep_mpi.py", line 18, in
swig_import_helper*
*    import _meep_mpi*
*ImportError: No module named _meep_mpi*

So it seems that it still isn't able to link properly despite my changes.

It may just be that the ubuntu packages just don't work well with this
version of python-meep.  If this is the case, where would you recommend I
get the packages for meep-mpi and libmeep-mpi, so that I can avoid these
problems I'm having?

Thanks again.
