Can't run trigger rally as normal user

[Marko]

Hi to all and sorry if this is a n00b question, i couldn't find info on the 
net. I installed Trigger rally sourceforge.net/projects/trigger-rally , an 
racing game using physfs that isn't maintained now, and i can't run the game 
as a normal user. physfs version is 1.0.1, the os is archlinux 2007.08-2 
Don't Panic and trigger rally is version 0.5.2. As you can see from the 
messages down running as root works without problems.
