BTW I'm hoping 4.6 is the last of the "monolithic tarball" releases, since we'll have new site up soon and will be able to set up nice repositories for packages etc.
We'll probably want to make various monolithic tarballs available (there's been talk elsewhere about various packagings that we might want to do and there needs to be much more talk) but we shouldn't be requiring every package to hit their mark when the core packages do.
The repository approach would allow Lars to finish bugtracker and release it (say) after 4.6 but before 4.7 for instance.
