Bugzilla 3 on Gutsy?

[Scott Ehrlich]

I installed a fresh copy of Gusty on a system and perform an apt-get 
install of bugzilla, mysql-server, apache2, postfix, and phpmyadmin.

The bugzilla home page on the server reveals it is version 2.22.1-debian2.

How can/do I upgrade it to 3?   Do I have to get the source and manually 
compile, or is there a trusted repo I can apt-get a newver version from?

I really want to also enable https (instead of http) and disable email 
support, so account changes (add, modifications, password changes, etc) 
can be done locally within the database.

Thanks.

Scott
