Rails - Feb 2006 - Problems running Planet Rails

I''m having problems figuring out why Planet Rails is giving me an
error.

I''ve setup the databases/config files and planet rails runs fine using
webrick, but when I try scgi server (instant rails), I get an:

Application error
Rails application failed to start properly"

I''ve also tried installing it to my asmallorange server and same thing
happens. Webrick runs fine, but apache serving it results in an error.

Any ideas what I should be looking at?

Thanks.
