I'm not sure.. I tried to find some slackware packages, but their site
is terminally broken..

Installing custom compiled versions of system libraries is typically a
recipe for a broken system disaster.. since it is difficult to know what
patches / fixes / compile options a distro will use to put together a
working suite.

On Ubuntu, the debug libraries are not installed in /usr/lib/..., they
hide in /usr/lib/debug/usr/lib/.... (Under /usr/lib/debug is an image of
the file-system, but just with debug libraries).

This means tools like gdb can use the debugging version of a library (or
grab its debug symbols at least), without affecting the run-time
performance of any other parts of the system.


If you had a spare HDD, installing Ubuntu (or one of the other more
modern distributions) would probably be the easiest way to proceed IMO.
