FWIW: we use the Libtool DL library for this kind of portability;

Do I have the libtool API calls available when linking against
libmpi.so ?
You should, yes.
Also, see my later post: doesn't perl/python have some kind of
portable dlopen anyway? They're opening your module...?
This should hypothetically allow you to do a simple putenv() before
calling MPI_INIT and then the Right magic should occur.
Is there any another way of setting a MCA parameter? Or playing with
the environment is the only available way?
