Setup error on OS X

[GoogleCodeExporter]

Running 'python setup.py install' on OS X with MPICH2 does not set up pypar
correctly, although the 'setup.py' script seems to run without any errors.
The following output is generated:

I'm also having this same problem installing on Mac OS X. Has this been 
resolved?

Unfortunately not, as far as I know. I ended up installing OpenMPI instead of 
MPICH2
and got it working on OS X that way
