Don't assume python2.5 is being used on successful hashlib import

The hashlib module has been backported to earlier versions of python. If
we assume that 2.5 is in use, then python will go crazy looking for
stuff that doesn't exist in earlier versions. This patch will allow
older versions of python installed alongside a standalone hashlib module
to work properly.
