On the use of pre-compiled classes in packages

[Julio Maia <julio@pobox.com>]

Regarding the following bugs related to some of my packges:
http://www.debian.org/Bugs/db/49/49557.html

I'd like to have a direction to follow regarding the use of pre-compiled classes in Debian packages. In other words, is really necessary to compile all the classes that go inside a Debian package, or is it better to use the classes usually provided by the upstream authors? I think it's wise to have this issue discussed and make it part of the policy.
