Starting tuxracer out of the box gives an error message saying that a directory /usr/share/games/tuxracer isn't found. Workaround: create this file as a symbolic link pointing to /usr/share/tuxracer.
i just emerged 0.61-r2 and ran it without a problem all the files were installed into /usr/share/tuxracer running `strings` on tuxracer and grepping for 'share' showed /usr/share/tuxracer ...
I'm not at home this week. So I can't access my gentoo PC now. I'll try find out more next week.
Sorry, my fault. I'm sharing my home directory between my debain and my gentoo linux installation. The file ~/.tuxracer/options was originally created by debian. This options file set tuxracers data_dir to /usr/share/games/tuxracer.
