[CIG-SHORT] problem with installation of pylith 64bit from source code

[Makoto Hoshino]

Dear pylith developers,

As written in the previous email from Ikuo, I have installed Pylith from
the source code into a 64bit computer machine with specification:

OS: CentOS release 4.4 (Final)
linux: 2.6.9-42.0.10.ELsmp x86_64
CPU(64bit): Intel(R) Xeon(R) X5355 @ 2.66GHz

As a note, I installed Python2.5 to /usr/local2/ and export
PYTHONPATH=/usr/local2/lib/python2.5/site-packages,
and installed pylith so that it does NOT depend on MPICH but MPICH2.

 No noticeable warning was found in the installation process of Pylith,
but I was not able to run it correctly. To be specific, I tried to run
Pylith in the directory src/pylith/examples/3d/hex8 by typing “ pylith
dislocation.cfg”. However, I only obtained the following messages.

Traceback (most recent call last):
File "/usr/local2/bin/pylith", line 31, in <module>
from pylith.PyLithApp import PyLithApp
File "/usr/local2/lib/python2.5/site-packages/pylith/PyLithApp.py", line
17, in <module>
from mpi import Application
File
"/usr/local2/lib/python2.5/site-packages/pythia-0.8.1.7-py2.5.egg/mpi/__init__.py",
line 14, in <module>
from _mpi import *
ImportError: No module named _mpi

Could you tell me what happened? I think the following information
obtained from the python shell is useful to make a diagnosis.
