It should work. That's the trick I used to play. Now I'm thinking that
your whole package management system is in some kind of weird stage now...
Aha! Kudos to Martin Krafft for figuring this out for me!
The problem: Specifying lpr_, cupsys-bsd+, and my custom tiem-cups-cfg+
packages on the command line to apt-get or aptitude.
a) lpr conflicts with cupsys-bsd
b) cupsys-bsd is a pre-dependency for my tiem-cups-cfg package
c) apt processes pre-dependencies *before* package removal (or at least
it appears to be the case in sarge).
When apt sees that it cannot install the pre-dependency package
cupsys-bsd, because lpr is still installed and in the way, it exits with
an error. apt isn't smart enough to take it one step farther and see if
lpr can be removed in order to resolve the pre-dependency conflict.
The (easiest) solution for me was to break package installation into two
1) Install/remove all non-"tiem-*" packages
2) Install/remove only "tiem-*" packages
Now things seem to be working propperly.
