Rails - Oct 2005 - Newbie routes(?) question

Hi,

I think this is a routes issue but am not sure.  I have a site that
has pages served from a standard "www.foo.com/" style address as well
as "UserDir" pages like "www.foo.com/~joe/".

I have tried to set up a rails app under one of these UserDirs and
when I attempt to get the base index page to display I get an error
page and the server log (Apache on Linux) says

    File does not exist: /<web-server-doc-root>/home

Can rails apps appear under UserDir sites?  Is this a routing issue?
If so how do I manipulate the routes?
