Modules not available on Knightly

The problem is probably caused by MODULEPATH not set.

# Knight
MODULEPATH=/cm/local/modulefiles:/etc/modulefiles:/usr/share/modulefiles:/usr/share/Modules/modulefiles:/cm/shared/modulefiles

# Cheaha
MODULEPATH=/share/apps/modulefiles:/share/apps/rc/modules/all:/share/apps/ngs-ccts/modulefiles:/cm/local/modulefiles:/etc/modulefiles:/usr/share/modulefiles:/usr/share/Modules/modulefiles:/cm/shared/modulefiles
