Id have to do some weird sed trick in the configure script and then reattach the -Wl,-shared for the rest of the configure script, and that seems like trouble to me. I guess that Im not that fimiliar with shell scripting to do that.
LIBS=echo $LIBS | sed s/\\-Wl\\,\\-shared//
LIBS=$LIBS -Wl,-shared

I not too fimiliar with what static versus shared means, but it seems like static would introduce more toubles like below.

Im not sure how to set up hardware acceleration. I read that openGL comes with Xfree86 and that ati has special drivers, but not for my rage 128 (i think thats what this old Dell i8000 has).

Is theres some way to replace libstdc++ with something else, like g++ or something? Are there some environment variables I can set that would clear this up? Could I downgrade gcc for this build, would that help?

rpm -I --old-package

Thanks for the speedy reply!
