BINGO!
Both of my problems are gone with this configure flag and the
make ends successfully, also with the --enable-shared configure
flag.

After installing (with the shared .so libraries), I also get
working mpi-compilers.

Note: when I do the above with the stable release 1.2.1,
I get again the following when compiling code:
  $ mpicc mycode.c
  gcc: dummy: No such file or directory
  gcc: ranlib: No such file or directory

But the good news is that the latter problem disappears
with the nightly built openmpi-1.3a1r14639.
Thus I'm looking forward to the next release that will
support my AlphaServers out-of-the-box.
 
Although I'm not at all an MPI expert, but if tests are
needed to help openmpi work on AlphaServers, then
I am willing to help with tests on my systems.

By the way: does OpenMPI support running MPI on a variety
of architectures? Can I run MPI code parallel on Intel-PCs,
HP/Itaniums and AlphaServers (all running Linux/CentOS) ?
Hence, is this kind of cross-architecture supported in OpenMPI?

Regards,
Rob.
