No warnings show up when importing the offending module:

Python 2.5.1 (r251:54869, Apr 18 2007, 22:08:04)
[GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
 >>> from sympy.mpmath import specfun
 >>>

So what could be suppressing the warning?
