David,

I did some investigation with this issue a while back. I think its a bug in the python port itself,
none of the lib-dynload libraries are linked to the main python library. For example, if you run
this:

setenv LD_PRELOAD "/usr/local/lib/libpython2.6.so" ; systemsettings

You should now be able to bring up the KDE printer interface. If you do this, you can see what
those libs are linked to:

# cd /usr/local/lib/python2.6/lib-dynload
# setenv LD_LIBRARY_PATH `pwd`
# ldd time.so
time.so:
 	libm.so.5 => /lib/libm.so.5
 	libthr.so.3 -> /lib/libthr.so.3
 	libc.so.7 => /lib/libc.so.7

I'm thinking that if we fix the python port to link these lib-dynload/* libaries to 
/usr/local/lib/libpython2.6.so the problem will go away. Investigating this now actually, but if somebody
else had ideas on this, please let us know :)
