Thank you Steve,

Could you send me the result of
printenv | grep SAGE
from the machine running sage-4.5.3.

printenv | grep SAGE gives (on _all_ installations)

that may be a problem on my machine.

I don't get the above with an import of mpmath. Just a thought, could it be mpfr-related. I'm using
