Ruby on Rails -- WEBrick OK, Apache isn't
 

I'm trying to get a Ruby on Rails application to work under Apache. It
works fine when run under WEBrick (via "ruby script/server"). I copied
the "public" directory (as well as "lib", "app", and "config") to my
preferred Apache directory (see below for details). As told in
instructions on a web page, I tried executing "dispatch.fcgi". It gets
a "Internal Server Error". Far below is the output of "ruby --debug
../dispatch.fcgi".

I'm running

fedora-release 3-9_2.rhfc3.at
ruby 1.8.4-1.fc3
rails 1.0.0
httpd 2.0.53
mod_fastcgi 2.4.2

activerecord 1.13.2
activesupport 1.2.5
fcgi 0.8.6.1
mysql 2.7
