Colin,

I was able to fix executable-hooks (which installing 1.8.6 under rvm was 
causing) per Michal Papas this morning. I;ve tried to instaull 
ruby-debug-base, etc. but:

gem install --remote ruby-debug
ERROR:  Error installing ruby-debug:
    linecache requires Ruby version >= 1.8.7.

(Incidentally, under rvm, if I were to install 1.8.7, would I need to 
reinstall all the gems I have installed under 1.8.6? Does rvm create 
another new, empty ruby "slot" in that regard that moves with the version 
selected?)

You are right, ruby-deub existed in my develoment.rb, which I commented 
out, restarted, and:

 ruby script/server
./script/../config/boot.rb:39:in `run': uninitialized constant 
Rails::Initializer (NameError)
    from ./script/../config/boot.rb:11:in `boot!'
    from ./script/../config/boot.rb:110
    from script/server:2:in `require'
    from script/server:2

Line 39 of boot.rb is:

Rails::Initializer.run(:set_load_path)

I'm really struggling with discerning what these error messages mean. It 
takes a while to get into the Ruby idiom, even longer using an old app, 
when you have been away from it for a few years (not by virtue of wanting 
to be away from it though) Rvic
