You should either add bin/boostpath/lib to the LD_LIBRARY_PATH environment variable,
or you should add -R bin/boostpath/lib/ option to the command line above -- in
addition to -L.

I have no idea about these. Could it be that your MPI is not installed system-wide,
but to a custom location? In that case, you need to do the same LD_LIBRARY_PATH/-R
dance for the corresponding library directories.
