No mounted valid Unreal Tournament CD has been detected while scanning all
"iso9660" and all "udf" filesystems in "/etc/mtab" for the file
"SYSTEM/UnrealTournament.exe". Make sure you mounted the disk correctly.
If it still doesn't work you can try setting the "_dist_dir" variable in this
PKGBUILD to your mount point or GOG directory manually. For the GOG release,
use the innoextract tool and set the variable to the output directory.
