Hi all,

What I did was reinstalled, but this time without the --include-dependencies.

gem install rails

This meant that for each dependency, I had to say yes. The install appeared to 
go through cleanly. I then did rails demo, and it did the right thing, and 
after this:

cd /home/slitt/work/demo
ruby script/server

I was able to pull up a rails generated page on http://localhost:3000.

I have NO IDEA why installing without the --include-dependencies would have 
made the problem go away, or even whether the thing that fixed it was just 
doing one more install of any kind. What I do know is I found out about 
running without --include-dependencies after google searching the error 
message, and that email thread suggested just gem install rails.

If anyone else asks about a "Could not find RubyGem rails" error, please tell 
them to try not using --include-dependencies, and please tell me what 
happened, as I'd like to find the true root cause of this problem.

Thanks

SteveT
