simply cd to $R_HOME/library/Rmpi/libs and do on the command line
ldd -r Rmpi.so
this will display you a list of dependencies of Rmpi.so and you can see
if you find there the libraries that you expected to link against, or
there will be some libraries from unexpected paths or missing ones

Dirk,
Configure concluded without errors. I am not running this on the HPC
cluster with icc, rather a separate local box used for testing and
learning. Its just an 64-bit Ubuntu 8.04 install on a 4-core machine.
LAM is not installed (I checked to make sure).
So, that leaves me with you last two options. Before I make my first
foray into using the R-debugger, I'd like to try you suggestion to
"Check ldd on Rmpi.so" but don't have a clue how to do so. Could you
instruct me?
Thanks to all for the helpful comments.
Mark

As Paul suggested, make sure you're not getting it mixed with
exisiting LAM headers or MPICH2 headers or, say, that you're getting your gcc
and icc experiemenst mixed up or ... ?
I control this by locally re-building the Debian packages for Open MPI. That
way I only keep one -dev package for MPI and can ensure that I do not get
mixups with other MPI installation. But then I do buy into the Package
Management mantra, but not everybody does...

Check ldd on Rmpi.so to ensure that you linked against what you thought you
should link against.
And if everything else fails, debug the compiled code and run R under the
debuggger. See the 'R Extensions' manual.

I'd join.
