rap script problem on slackware

[Jacob Schmude]

Hi

I'm trying to play the streaming interview realaudio file, but rap won't
work now that I've installed slackware. I can't see anything wrong with
the script and realplayer claims it can't open the display. But the
display environment variable is set in the script and this was working
fine on debian when I was using that. I got the realplayer RPM from
realplayer web sight and converted it with rpm2tgz and can't see what went
wrong. Xvfb is also installed.
