The real test to see if ATK 2014 is supported is to check your gcc version. You can type "gcc --version" to find out. If it is below 4.2, you cannot run ATK on this machine.
The Linux you are using is indeed old, but there are more recent updates (patchlevel 4 was released in 2011, the one you have is from 2008). I don't know if upgrading to that would help, or if you need OpenSUSE 11, which we know for sure works. I think - without being able to confirm it quickly - that patchlevel 3 contained gcc 4.2.
