Ok, here's something funny/weird/stupid: Looking at the actual mpi.mod module file in the $OPENMPI_HOME/lib directory, the very first line is: GFORTRAN module created from mpi.f90 on Fri Sep 19 14:01:27 2008
WTF!? I specified that I wanted to use the ifort/icc/icpc compiler suite when I installed (see my first post)! Why would it create the module with gfortran? This would seem to be the source of my troubles...
