I just uninstalled MegaGlest 3.5.0 beta 1 using the uninstall-megaglest.sh script.
The uninstaller doesn't remove the 'lib' subdirectory which contains the symlinks the start script creates:
tomreyn@thatatitower:~$ ls -lah megaglest-3.5.0-beta1/lib/
total 8,0K
drwxr-xr-x 2 tomreyn tomreyn 4,0K 2011-04-13 02:15 .
drwxr-xr-x 3 tomreyn tomreyn 4,0K 2011-04-13 02:15 ..
lrwxrwxrwx 1 tomreyn tomreyn 27 2011-04-11 22:50 libdirect-1.2.so.0 -> /usr/lib/libdirect-1.2.so.9

In a way that's correct since those symlinks were created by the start script, not the installer. On the other hand i think one would want those removed when uninstalling...
