ERubyRun eval error on Fedora Core 3

I am sure this is something I have screwed up, but I would
be grateful for help.  I have been putting this off hoping
to work it out myself, and now a week has gone by ....
I am baffled, and some Google searches indicate there is
others have this problem, but I have yet to find a solution
that works.  Any help would be appreciated.

Here are the details:

I just built (and I would have thought properly installed)
mod_ruby 1.2.4 -- this is on a system that was happily
running an older version of mod_ruby prior to its upgrade
to Fedora Core 3.  This system has:

mod_ruby 1.2.4
ruby 1.8.2
apache 2.0.52
linux 2.6 kernel

mod_ruby.so is in /usr/lib/httpd/modules
ruby-run.rb is in /usr/lib/ruby/1.8/apache
eruby-run.rb is in /usr/lib/ruby/1.8/apache

When I visit a .rhtml page, I get:
[Thu Mar 03 17:36:56 2005] [error]
mod_ruby: error in ruby\n(eval):45: (eval):45:
uninitialized constant Apache::ERubyRun (NameError)\n\tfrom (eval):45:in `value'\n

I have all the apache config stuff in a file
/etc/httpd/conf.d/mod_ruby.conf as follows:

LoadModule ruby_module modules/mod_ruby.so
