To make it simple, I now have only one version of rails, and that is
2.3.4. So I uninstalled both ruby-debug and ruby-debug-base, then
re-installed them, with apparently unflawed success. I tried again to
invoke the rails server with the --debugger option, only to receive
the same complaint back - namely, that I need to gem-install the ruby-
debug gem. For yucks, I verified that the debugger itself still seems
to be working fine, thank you.
And so I'm stuck here. I"m convinced I'm going to have to drop down to
the debugger at some point in my further explorations with rails,
and I wish like hell I knew how to do that.
Still seeking the answer. At this point, waiting for inspiration.

You need to install ruby-debug to run the server in debugging mode.
With gems, use 'gem install ruby-debug'
depot 507 ->ruby -r debug ./foo.rb
Debug.rb
Emacs support available.
./foo.rb:2:a = 1
(rdb:1) l
[-3, 6] in ./foo.rb
1
=> 2 a = 1
3 l=""
4 while l
5 puts "hello"
6 l = gets
(rdb:1) n
./foo.rb:3:l=""
(rdb:1) quit
Really quit? (y/n) y
depot 515 ->
then as superuser I installed ruby-debug, and all went well.
