mpi4py support

Hello,

I support an IBM AC922 system with InfiniBand, Spectrum MPI, and the xl compiler. We rely on PowerAI for delivering customizable python environments backed by an ecosystem of pre-tuned machine learning packages. We were recently asked to support mpi4py and I have been unable to compile it in a conda environment. It will compile with the system python, so xl and spectrum seem to be configured fine - issues only arise in a conda environment. I'd appreciate any help.

Thanks,
Greg
