I suggest the dependency on OpenAL be mentioned somewhere on the RO download web page. I guess most tuxgamers have it installed already anyway. I just happen to have a quite fresh installation. (and is geeky enough to be using slackware)
The svn version (as of today) of OpenAL doesn't work with RO. (sigsegv's)
The RPM version works however.
I have sound! I have sound! Rock and roll!
