what kind of Cray system are you compiling NWChem for?
The instructions you are following are for the Cray XT that has been around for almost 8 years ... is this the system you want to install NWChem on?
If you scroll down a little bit at the URL http://nwchemgit.github.io/index.php/Compiling_NWChem#How-to:_Cray_platforms
you will find instructions for more recent Cray platforms.
