Hmmm, OK. Then why does setting RUBYOPT to just rubygems work (it has
no dash?) That doesn't work on the command-line (at least on Windows):

C:\_Ryan\ruby_installer\svn\NSIS>ruby rubygems -e 'puts "hello"'
ruby: No such file or directory -- rubygems (LoadError)

C:\_Ryan\ruby_installer\svn\NSIS>ruby -rubygems -e 'puts "hello"'
hello

Maybe to be safe I should always just add -rubygems (i.e with a dash prefix.)
