Those are good hints...

Debian and Ubuntu have excellent package management functionality and
and repositories (as good or better than any other major Linux or Unix
distribution, AFAIK), but strangely, by default they have no
consistent API or command set for using it.  Therefore, I recommend
trying out wajig:

  sudo apt-get install wajig
  http://www.togaware.com/linux/survivor/Wajig_Overview.html

It's really just a wrapper (in Python) around all the same underlying
command-line tools, but in my limited use of it so far, it seems
noticeably more convenient than the traditional bizarre, non-orthogonal
mishmash of apt-get, dpkg, apt-cache, apt-file, etc.
(I don't know if/how it compares to aptitude, I've never used that.)

The Debian package management tools don't seem to have any sane
programming API, but so far I haven't really needed that (and wajig
manages to do without).

Their only other major flaw that I'm aware of, is that, just like all
the rpm based tools, you can only have one single version of a binary
package installed at a time (yuck!).  Perhaps one day, the sort of
tools the NixOS and DragonFly BSD folks are working on will fix that.
