That's interesting Steve! That may be due to a change in sage-4.6.
Can you try "import sage.all" on the machine with sage-4.5.3?
I was going to email to both sympy and mpmath mailing list but that's
something I'd like to know before raising the issue on mpmath.

I think the "import sympy" in setup.py is wrong in any case.
