Since the LGPL was designed to allow propritary software to link to a 
LGPL module, I don't see why any software under a free license like 
Python cannot link to the GMP library.  The PSF may want you to release 
gmpy under a dual license if it is incorporated into the Python standard 
library but I don't see why that cannot be done.
