[gentoo-amd64] Dropping qt-3

[Mark Haney]

I'm a little curious.  I've got two versions of QT (3 & 4) on my system.
 That's not a problem as I have multiple python versions too. What I"m
curious about is when will it (or is it) safe to unmerge qt3?

It's not a system package so you can remove it whenever you want without 
any ill consequences.  If something else needs it, it will pull it back 
automatically.

To save you a needless rebuild in case something pulls it back, the best 
way to know is to simply remove all instances of x11-libs/qt* from 
/var/lib/portage/world (if it's there) and then run "emerge -a 
--depclean".  This will remove it if it's no longer needed.

It is safe to unmerge qt3 while you are not using any application depends on
it.

Do 

equery depends qt

and see how many packages depend on qt3 (=x11-libs/qt-3). Mainly, it is
kde-3.5 that has to have qt3. If the dependence is conditional on qt3, then
you can avoid it buy recompiling the package with USE='-qt3'
