Debian contemplates patch management

I'm guessing you're talking about vpim :)
It looks like the vpim package was removed last year because it went unmaintained. You'll
still see references to it as it was part of a stable release, but it won't be included in
future releases. Unless somebody repackages it of course -- if you're interested in doing that
yourself, check out mentors.debian.net and the debian-mentors mailing list.
