Yes, I run into similar problems when trying to upgrade sympy in Sage. We ship our own version of mpmath, because different versions of mpmath are not compatible with each other (e.g. you can't just depend on mpmath externaly, there are little things that break). However, we do try to update mpmath in sympy, for example the latest git sympy is using the latest release of mpmath. But you can see the related commits, that it's not as trivial as just replacing the code. If you know any solution, it'd be absolutely awesome. One solution that I can think of is to drop python2.4 support, and use relative imports in sympy to use our own versin of mpmath, that is tested and works. That way it should not interfere with the other installation of mpmath, that the user might have (in Sage or else).
