Hi Patrick,

Okay, those are lots of good ideas. I'll chip away at them over the weekend. But, you are right, I am just trying to build glib. I'll let you know how things turn out. I'll definitely look into those library path ideas you have. I didn't know what was happening under the hood. I also want to try Sergei's ideas. As for version, I don't know which version you are referring to, but I am running Debian Linux 6.0.6 AMD64.

Have a great weekend,
Chris
