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
Durga

Calin,
Look like you're missing a proper value for the LD_LIBRARY_PATH.
