Ok, I did something stupid. I have two similar ubuntu systems. Noticing that some packages I need are missing on one but not knowing which ones,
I did a list of them using:

dpkg --get-selections > installed-software

Then I used grep to weed out only the installed ones, and went to the other system and entered:
dpkg --set-selections < installed-software

Then I tried to do a dselect, which wants to delete several packages I really want to keep. Is there any way to keep those packages? Or at least find out which ones are forcing removal of it, so I can deselect them?
aptitude has a reverse dependency tracking tool. You can look at a package, and ask "which package X on it", where X can be, among other things, conflict. This should tell you which packages are causing your package to be removed.
