[Building Sakai] Issue with Sakai Proxy passing?

[Benjamin Willard]

I get a internal server error with this setup but I am sure I am doing 
something wrong.  I am trying to figure out how to make my website 
http://compass.biblestudylms.com:8080/portal become 
http://compass.biblestudylms.com/portal without the 8080... Any help would 
be much appreciated.

I am using Ubuntu Server, with Tomcat 5.5.33, Apache 2, Sakai 2.7.1

<VirtualHost *:80>
