[Prboom-users] Cannot start!

[OSx <fe...@ma...>]

Hi, I installed everything correctly, but when I try to start prdoom I get the following message:
IdentifyVersion: IWAD not found

I don't get this because I have the wad files:
$ ls /usr/local/share/games/doom/
doom1v18.wad  prboom.wad


My distro is Yellow Dog Linux 2.1.

any help appreciated
