Installation segfault

[jokerwww]

Hi,

I purchased Penumbra: Overture through the Humble Indie Bundle and have finally gotten around to it, however I'm having trouble with the installation segfaulting:

$ ./penumbra_overture_1.1.sh
Verifying archive integrity... All good.
Uncompressing Installer for Penumbra: Overture.............
Uncompressing sub archive............................................................
Collecting info for this system...
Operating system: linux
CPU Arch: x86

./startupinstaller.sh: line 134: 8219 Segmentation fault `pwd`/$FRBIN $ARGS

I have attached the output of running the installer with "sh -x". I haven't attached the hpl.log because "~/.frictionalgames" was not created.

I'm running gentoo ~x86 on a intel core 2 duo, 2GB RAM, NVIDIA 8600M.

Help would be apreciated.

P.S. I've checked the md5sum of the install file and it is correct.
