## /share/apps/mpich2/3.1.4/gcc
## /share/apps/fftw-3.3.4/gnu/lib
## /share/apps/atlas-3-10-2/gnu/lib (Atlas libraries for lapack and blas, tuned version)

### default mpic++ is from

## python-devel.x86_64 is installed. Check this out by typing 'which python-config'. If it returns /usr/bin/python-config, then it is fine. Else yum install python-devel.x86_64.
