I do not care about GP at all (at least when Math::Pari is
considered).  What is required is the part of the library which is (by
unfathomable reasons) not installed (the graphing and highlevel stuff).

I saw internals of the (new) Math::BigInt, and it has very little
chance to be quick - no matter what the backend is.

Well, this is a good testbed for PARI.  ;-)
