Tibia in Linux problem

[tigerx2]

dcdourado@lgnetbook ~/Programas/Tibia $ sh StartTibia.sh
./Tibia: ./libc6/libc.so.6: version `GLIBC_2.11' not found (required by /usr/lib/libGLU.so.1)

How can I fix this ?

Obs: I can run tibia normally by clicking in it icon, but it is a little slow (game interface).
Thank you.

I don't know, i haven't used Linux in a while... also every time i used it i ran back to windows coz i just couldn't get used to it.
Anyways "GLIBC_2.11'" seems to be not found so i did some googleing...
If i were you i would try these tips out.
