Ergo, you could drop that rpath.
I agree that when you want to rebuild everything and the kitchen sink as
a user, you have to use such things (or --with-foo=, or LDFLAGS, the
latter two being possibly better when viable). But as far as diagnosing a
possible misbehaviour goes, you should first take it out.

If you force the linker really hard on putting your target installation
directory first, you should be ready to face the problem that a
pre-existing library takes over. Which is exactly what is happening here.
Mpfr and gmp (up to 6.1.2) differ precisely in this aspect. See the
thread that vincent pointed to on this mailing list.

Looks like Real Fun...
