Right.  My point was if the OFED install.pl script thinks that having  
mvapich installed means installing mvapich_gcc, as you probably  
already have Red Hat's plain mvapich installed, there is a good chance  
you might get file conflicts or other problems attempting to install  
mvapich_gcc, so it would never get installed, so install.pl would  
crash out.  If you change install.pl to expect just plain mvapich/ 
mvapich2 for the gcc versions, it might just magically start working  
(although using our packages, not the OFED packages).
