I've been trying for many days to get Red5 to install on Ubuntu 10.04. I finally managed to get red5.sh to stop hanging a few seconds in but now I'm getting the following error:

Setting default logging context: default

I suspected that this had to do with slf4j not being installed or on my classpath. I installed logback and libslf4j-java from aptitude and I see related files in my red5 lib directories. For example:

/usr/share/red5/lib/slf4j-api-1.6.1.jar
/usr/share/red5/lib/log4j-over-slf4j-1.6.1.jar
/usr/share/red5/lib/logback-classic-0.9.26.jar
/usr/share/red5/lib/logback-core-0.9.26.jar
/usr/share/red5/lib/jcl-over-slf4j-1.6.1.jar
/usr/share/red5/lib/jul-to-slf4j-1.6.1.jar

And I set my classpath to /usr/share/red5/lib/

Any ideas on where to proceed from here? There seem to be a lot of people having trouble getting 10.04 and red5 0.9 working together. I've tried red5-0.9.1.tar.gz and red5_0.9.0-RC1_all.deb. The libraries above should be all that are needed according to Red5's documentation and I got the latest version of each.
