original windows-message in german:
'Der Befehl "ruby" ist entweder falsch geschrieben oder konnte nicht gefunden werden.'

may be in english: 'The command "ruby" is misspelled or could not be found'

Reason:

jruby\lib\ruby\gems\1.8\gems\ruby-debug-0.10.4\bin\rdebug -- line: 115
output = 'ruby -c #{Debugger::PROG_SCRIPT.inspect} 2>&1'

would work if i have any ruby.exe in my (windows-) path.

Works when i change "ruby" to "jruby".
