You gave the answer yourself.
Chrooting does not automatically mean your SO cache is where it should
be for the target system.
Perhaps your livecd is newer/older than the target system or simply the
python in live environment
is not (most likely) compiled as the one in the target system.
That is _one_ reason I stoped using gentoo and switched to debian/ubuntu.
