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
