You can build a gp.so which is linked against the libpari.so.
We cannot provide a rigid interface for GP internals anyway.

base perl install, but the GMP support is optionnal and need to
be installed separately).

Does they use more than modular arithmetic ?

I agree, I always found that was strange.
