I'm going to assume that you're running on Windows -- because
you usually are :) The answer, then, is that pure python modules
would need to be reinstalled into (or at least made visible to)
the newer Python version, but that extension modules would need
to be recompiled against the newer version -- possibly making use
of a precompiled binary.

Just to try, I've compiled Durus without issue on Python 2.6
from the tarball on their website:


but it's not clear from your message above whether it's the
build which is the issue or some aspect of using it. Can
you clarify? I'm quite happy to post up an .msi or something
for you to use if that'll help.
