The errors you are seeing aren't related to using g95 vs. gfortran:
1. The warnings from configure are fairly normal. It's just configure
trying to be responsible and telling you things that you might want to
know (e.g., your system has no support for Fortran INTEGER*16, so OMPI
is not including support for MPI_INTEGER16).
2. The problem you are seeing is simply that your installation library
directory is not included in your linker default search path. You can
typically fix this by prepending your LD_LIBRARY_PATH environment
variable. See http://www.open-mpi.org/faq/?category=running#run-
prereqs.

I went through the compile process with openMPI - twice, using g95
and gfortran (the default install on my openSuSE11.0 setup). It
seems to have trouble finding the libraries, in particular libopen-
pal.so.0
I've seen shared-library problems with some x86_64 packages that I
contrib to SourceForge and I'm wondering if this is a known problem
with openMPI? I'm using a TYAN 32-processor SMP machine with
openSuSE11.0 installed. (I tried copying the shared object file(s)
to /usr/lib and /usr/lib64)
This is STDERR output, the first time with g95 and then with gfortran:
