Mine is compiled for glibc2.

It's a circle with a triangle on the right hand side of the triangle 
that has a 'C' in it.

No, I have one, its just I have a slim CD-ROM drive that doesn't have 
one of those connectors, it will only play CD music through the onboard 
sound which has unfortunately died on my computer.

Besides the one that won't play with my drive (it's the physical drive's 
fault, it doesn't work in DOS/Windows either), I've been able to rip all 
of my CD's without issues with my new version of cdda2wav. By the way, I 
use the GRIP frontend to cdda2wav.
