Hi Anthony,
thanks for the quick reply.

Nothing there.

MPICH2 Version:    	1.2
MPICH2 Release date:	Unknown, built on Mon Oct 19 17:12:54 EDT 2009
MPICH2 Device:    	ch3:nemesis
MPICH2 configure: 	--prefix=/home/truedas/local/ --enable-debuginfo
MPICH2 CC: 	gcc  -O2
MPICH2 CXX: 	c++  -O2
MPICH2 F77: 	g77  -O2
MPICH2 F90: 	ifort  -O2
So indeed, I have overlooked the g77 entries in the configure log or 
searched for the wrong thing, sorry. Why does it choose different 
compilers for the two Fortran flavors, and what should I do to make the 
Intel compiler work with MPE?
