I'm using Slackware 12.1 and so far I've been unable to find any packaged debug libraries.  I'm 
tempted to compile them myself with debug enabled but I expect that to take a little while mostly 
because of the effort of locating the proper libs.

How different are Ubuntu's libraries (packages) compared to the bone stock ones straight from the 
project developers?   I'm not certain they would really work on Slackware.

I was wondering about the ??'s.  Thanks.

If I can identify the proper source code for the libraries then I will get another back trace.  But 
it may take me a little while.  I'm using system tools like 'locate' to try and find out more.  Are 
there any library tools that might help me identify them?

I was fairly certain that I was compiling with "-g" but I looked at the config.log and verified that 
I am.
