Glibc error preventing installation

./ThinkTanks_v1.1.sh.bin
Verifying archive integrity... All good.
Uncompressing ThinkTanks............................
./setup.sh: line 264: 24067 Segmentation fault      "$setup" "$@" 2>>$NULL
The setup program seems to have failed on x86/glibc-2.1

Attempting to install 1.1 on Gentoo 1.4 as a server only. No graphics libraries were installed because this is a headless server with no X.

Because of that error though I installed glibc 2.3.2-R1 .

It doesn't seem to like glibc even after I have installed it. Could TT not be happy with this newer version of glibc? It seems to be looking for glibc-2.1 specifically no?

Any suggestions on how to overcome that error?
