Well, that help me realize that there are people who type a lot
faster than me :) Thanks Justin for your accurate answer.
The only thing here is that in this particular case is not gcc who
does not find the library (the error does not happen at compile time)
but the runtime linker. So /etc/ld.so.conf is definitively the problem.

On a number of my Linux machines, /usr/local/lib is not searched by
ldconfig, and hence, is
not going to be found by gcc. You can fix this by adding /usr/
local/lib to /etc/ld.so.conf and
running ldconfig ( add the -v flag if you want to see the output ).

I knew that was the answer to Calin's question, but I still would
like to understand the issue:
by default, the openMPI installer installs the libraries in /usr/
local/lib, which is a standard location for the C compiler to look
for libraries. So *why* do I need to explicitly specify this with
LD_LIBRARY_PATH? For example, when I am compiling with pthread
calls and pass -lpthread to gcc, I need not specify the location of
libpthread.so with LD_LIBRARY_PATH. I had the same problem as Calin
so I am curious. This is assuming he has not redirected the
installation path to some non-standard location.
Thanks

Look like you're missing a proper value for the LD_LIBRARY_PATH.
Please read the Open MPI FAW at http://www.open-mpi.org/faq/?
