One of these things is not like the other!

Kyle,

Thanks for the clue-bat when I couldn't setup a chroot. It's working great now.

apt works fine from the chroot, but packages that rely on threads are broken.
Packages relying on pthread_push_cleanup, and pthread_pop_cleanup are
also broken since we have bugs in those functions according to the
testsuite.

Cheers,
Carlos.
