Error when installing pyzoltan on Cray cluster

[Bastien Bodin]

Hi everyone,

I am installing pysph on a Cray cluster, and after specifying the different MPI flags on the ~/.compyle/config.py file, I encounter this error (at the end of this message).

Could it be linked to an error when installing Zoltan? Is it a problem due to the version of one of the dependencies?

Best regards,

Bastien
