For SuSE, you just either need to export it when you open a new 
konsole or else just stick it in the user's .bashrc (.profile 
doesn't seem to affect KDE konsoles) You bascially only need to 
do it once for a konsole session if doing it manually. It 
affects both PyQt and PyKDE.

kaccelbase.h is in the extra/ subdirectory and is taken from the 
kdelibs source tarball for the appropriate version. There are 
half a dozen or so .h files that are necessary but not usually 
in kde3/include (and a few h files that need some mods to work 
with sip or my code generator). Those h files are all included 
with PyKDE under extra/ and build.py points the make files to 
the correct versions (eg extra/kde303/kaccelbase.h). 

virtual_hook (if I remember correctly) was just kind of 
arbitrarily added all over the  place one day by someone back in 
the KDE 2 or early KDE 3 days. There's some discussion on one of 
the KDE lists, and some of it is fairly unfavorable. It was 
apparently added for some debugging reason that didn't seem real 
necessary to me, and it pops up from time to time and causes me 
headaches.

It doesn't cause any problems here on any version, but it should 
break everything - kind of scary that it doesn't. It shouldn't 
be possible to load a lib (PyKDE module) with unresolved 
symbols.
