Cannot connect to debugger using Rails 3 and RVM

[mrthebob]

Hi! I'm using rvm and Rails 3 (with Ruby 1.8.7), and I'm trying to get the debugger going. I've done:

gem install ruby-debug-ide

I also have the latest vim-ruby-debugger

I've tried all sorts of combinations with the :Rdebugger command (like :Rdebugger 'script/rails server', etc etc). If I look at the log file I get a whole bung of this:

Vim plugin, 17:21:13: Executing :Rdebugger...

I can't seem to figure this out. Any hints?

Many thanks!
