I had a similar if not the identical problem when I upgraded from
python 2.4 to 2.5 on a test system under cygwin (no chroot).

It turned out that Python 2.4 had been installed with prefix = /usr
(library in /usr/lib/python2.4) and Python 2.5 was installed with
prefix = /usr/local (library in /usr/local/lib/python2.5).

I think I could have fixed it with a few symlinks, but I wound up
removing and reinstalling python 2.5 with prefix = /usr.

Perhaps this will help you figure out what you need to do.
