[gentoo-user] kde:3.5 how to phase out

[Helmut Jarausch]

Hi,

I'd like to phase out KDE:3.5. One reason is, that I cannot install
both, 3.5 and 4.2 without using 'prefix'.

For doing so, I need to find out which (installed) packages use which
parts of KDE:3.5. Is there something better than unmerge all of KDE:3.5
and let revdep-rebuild find out.

Furthermore, how to unmerge all of KDE:3.5, e.g. 
emerge --unmerge kde-base/kde-meta:3.5
does not work.

Many thanks for a hint,
Helmut.

Did you install by using kde-meta or some of its friends?  If so,
unmerge the meta package then run emerge -p --depclean and make sure you
are not loosing anything you want to keep, then run revdep-rebuild to
make sure all is still sane.

Also, you can remove anything kde 3.5 in your world file, then run
depclean to remove it.  Keep in mind that the world file supports
version specific lines now.

I'm sure some other guru will come along with other ideas but one of
those should work.  May not be perfect but is anything ever perfect?

Some of your questions are answered here, right on the top (I hope I
link to the up-to-date version and not the outdated one):

http://www.gentoo.org/proj/en/desktop/kde/kde4-guide.xml
http://www.gentoo.org/proj/en/desktop/kde/

I don't know if my advice beyond those links is of any use as I did it
all the "wrong" way -- didn't unmerge previous kde, just unmasked the
new kde versions, didn't use sets, still have USE="-kdeprefix" etc.
Still, sky didn't fall on me, at least not until I unmasked the
then-unstable xorg 1.5 ...

How about this?

$ equery d kdelibs:3.5

Unmerge whatever kde:3.5 packages you installed by hand then use
--depclean to clear the dependencies.

paludis --uninstall --with-dependencies =kdelibs-3.5.9

If you have openoffice installed, it will need to be compiled without
the kde use flag.  Also to compile it make sure you have a default boost
selected by using eselect boost.

Afterwards you may want to package.mask =kde-base/kdelibs-3.5*

A revdep-rebuild is probably in order too.
