Still, can you determine which library defines mprealmod_mp_mpeq_?
I would always start from that when having undefined symbol problems.

There is no direct solution. However, though I don't see how that
would fix the original problem, you can try the following:

1) build extension module with f2py as above
2) copy the linking command of the f2py build output and
replace gcc with g++ and rerun the linking command.

This way you can test whether the new extension module linked with g++ 
imports or not.
