even with this setup you could install an Open MPI version or other software
for your own usage if necessary. I put such stuff usually to ~/local, i.e. to
build Open MPI:
$ ./configure --prefix=$HOME/local/openmpi-1.4.2
and after `make` / `make install` add the paths "$HOME/local/openmpi-1.4.2/bin"
and "$HOME/local/openmpi-1.4.2/lib" to PATH resp. LD_LIBRARY_PATH to access
your newly installed software (e.g. in ~/.bash_profile).
