How did you configure those prebuilt gmp/mpfr/mpc libraries installed under
your home directory?  In particular, did you configure them all with
--disable-shared?  If not, then you have to be extremely careful to avoid
unintended mismatches, and in some cases incorrectly duplicated state.

I know for a fact that prebuilt gmp/mpfr/mpc installed in a private location
works fine on powerpc64-linux when all are configured with --disable-shared.
