Bug#572420: Please change this bug to libsdl1.2debian

[Rick Thomas]

I own both G3's and G4's running Debian Stable.  I can take them down  
for limited periods (a day or so) to run other versions of Debian.

If someone who knows what he/she's doing can walk me through the steps  
(I'm an experienced system admin.  But I'm not a developer.) I'm  
willing to do whatever needs to be done to get this bug fixed.

Let me know where to begin...
