I can point you to several posts of people with messed PATH and ended
with problems installing gem, just a few weeks back, here on this


I got several mails to my inbox about Mongrel too, and some "new" ones
for One-Click Installer...

So the thing is: if JRuby uses RubyGems, and 'ruby' executable is
labeled 'jruby', why not name rubygems 'jgem'?

In any case, there should be a warning or something if another ruby
implementation is in the PATH...

I don't know how to fix this and makes everybody happy...
