As Tim points out, there have been no changes to the mpiicc and mpiifort scripts in Intel MPI Library 3.2 Update 1. Perhaps your environment is not setup correctly and, when using the Make.UNKNOWN makefile, it's unable to see those commands?
Can you make sure that you're sorcing the appropriate
mpivars. script before running
make? They should be located in the
(for 64-bit machines) directory.
Let us know how this helps.
