[mod_python]apache chroot

I'm using a working chroot for apache, built with mod_security on a gentoo-box.

Using "SecChrootDir /chroot/apache" in 99_mod_security.conf, forced a
failure at any access to .psp files with this log:
[code]
make_obcallback: could not import mod_python.apache.\n
[/code]

I tried to populate chroot with a lot af files, but with a serious strategy.
What is needed to have a working chroot for mod_python?
