Concerning the joint use of --with-gmp-build= and --enable-shared, I guess the problem is that the dynamic linker/loader must be taught where to find the GMP library just build. What might be a portable way to do that?
The problem is that @extra_libraries@ was not set for ppl-config. Here is a better patch, using libtool to find gmp libs:
