Jeff is correct. The Intel environmental variables are either set in /etc/profile or /user/.bashrc (or manually). Root sets its own environmental variables and therefore the key is to make sure that the environmental variables are set before an installation as root is done, i.e.:

source /opt/intel/Compiler/11.1/073/bin/ intel64
source /opt/intel/Compiler/11.1/073/bin/ intel64

Then the rest of the procedure can follow.

It sounds simple and it is, perhaps

Make all gets the same environment as make install (assuming you do it in the same shell). But if you sudo make install, the environment may be different - it may not inherit everything from your environment. 

I advised the user to "sudo -s" and ten setup the compiler environment and then run make install. 

Sent from my phone. No type good.
