Hi Brett.
   Thanks for responding.

   I have both qt3 and qt4 installed:

mark@lightning ~ $ eix -I x11-libs/qt
[I] x11-libs/qt
     Available versions:
        (3)     3.3.4-r8 3.3.8-r2

   As far as I can tell Myth and most everything else does depend on qt3:

mark@lightning ~ $ equery depends =x11-libs/qt-3.3.8-r2
[ Searching for packages depending on =x11-libs/qt-3.3.8-r2... ]
app-cdr/k3b-1.0.1 (=x11-libs/qt-3.3*)

mark@lightning ~ $ equery depends =x11-libs/qt-4.2.3-r1
[ Searching for packages depending on =x11-libs/qt-4.2.3-r1... ]
app-text/poppler-bindings-0.5.4 (qt4? =x11-libs/qt-4*)
mark@lightning ~ $

   I did upgrade mysql to version 5 so I'll try rebuilding qt3 using
this command:

emerge -av =x11-libs/qt-3*

   If the info above suggests other ideas please post back when you
get a chance.

thanks,
Mark
