Installation stalled on Kubuntu Lucid

[Sbirulinux]

Ok, I decided to kill the process in the meantime, and install it again, this time in home rather than usr/local/games. It worked, and didn't stall. However, I was unable to start the game by the menu entry. From Konsole I get:

./penumbra.bin: ./lib/libCgGL.so: no version information available (required by ./penumbra.bin)
./penumbra.bin: ./lib/libCg.so: no version information available (required by ./penumbra.bin)
Penumbra: Overture exited unexpectedly, please check
/home/Sbirulinux/.frictionalgames/Penumbra/Overture/hpl.log
for any error messages
Also try running
ulimit -c unlimited
And re-running Penumbra and try and recreate the error
then submit the generated core file or stack trace

Finally, in the log I read:

What does all this mean? Was this the reason why it wouldn't install the first time? Can I still run the game somehow? Thanks!
