libQtGui.so.4 and mythtv 0.20 [solved]

[Jykke]

I unmerged quite a bit from my box and noticed that I had also inadvertly installed qt4,
which should be no-no for mythtv. Well now I get:

# emerge -p --unmerge qt

>>> These are the packages that would be unmerged:

x11-libs/qt
selected: 3.3.6-r1
protected: none
omitted: none

so the version should be ok - but mythtv is giving me following:

# mythbackend
mythbackend: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory

I, however do have this lib file under /usr/lib/qt4 so what gives?
Is it normal or is it leftover from my qt4 detour? If it is normal how do I get mythtv informed about the existence of the
said library?

revdeb-rebuild treats me with following but do not fix a thing:

# revdep-rebuild -pv
Configuring search environment for revdep-rebuild

What should I do?

I also uninstalled kde during the process - cause I don't need it so what is this stuff that is missing kde?

Help appreciated

EDIT: it seems that somewhere during the updates emerge --syncs and other stuff I had updated to KDE 3.5 and
obviously to qt4, which is nono to mythtv. Load of emerge --unmerges later system stripped down to the bone
no kde anymore and so on I got mythtv 0.2 installed. This particular problem was caused by couple of
libs still refering to qt4 libraries qfile and delete was the answer.
