GLIBC_2.14 and GLIBC_2.15

Hello,

I’m trying to install skycat and when I try to run it it tells me:

/lib64/libc.so.6: version `GLIBC_2.14’ requiered by /home/…/libtk8.4.so

/lib64/libc.so.6: version `GLIBC_2.15’ requiered by /home/…/libtcl8.4.so

I have the openSUSE 11.4, I tried looking for the library and install it, but it doesn’t work, how can I download it?
I am not so familiar with openSUSE yet

Please!

thank you
