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 :)
