Its there:
# which mpif90
/opt/mpich2_107_GNU/bin/mpif90

# echo $MPIF90


 or because it is there and

It works:
# mpif90 samplempi.f -o sample
# ./sample
 node           0 : Hello world


or because configure doesn't like the name

Removed MPIF90=/opt/mpich2_107_GNU/bin/mpif90

$PATH is set to MPICH2_GNU.
