Penumbra Collection - frontend error

[Linux.Blue]

Back a few versions (MandrivaLinux that is), this game has worked well. I don't know why now. I am not sure if it's 2010.1, the kernel I am using, the KDE version, or what, but this is what I get:

[jeremy@localhost Downloaded Files]$ sh PenumbraCollection-1.1.sh
Verifying archive integrity... All good.

What is a frontend? something that is simply to find?
need more info?
