Subject: Re: Which Ruby is in use?

In 1.9:
RUBY_COPYRIGHT  
RUBY_DESCRIPTION String Version number 1.9 & interpreter arch.
RUBY_ENGINE String The name of the Ruby interpreter
RUBY_PATCHLEVEL  
RUBY_PLATFORM   

Results in irb:
ruby-1.9.2-head > RUBY_COPYRIGHT
 => "ruby - Copyright (C) 1993-2010 Yukihiro Matsumoto"
ruby-1.9.2-head > RUBY_DESCRIPTION
 => "ruby 1.9.2dev (2010-07-14 revision 28640) [i386-darwin9.8.0]"
ruby-1.9.2-head > RUBY_ENGINE
 => "ruby" 
ruby-1.9.2-head > RUBY_PATCHLEVEL
 => -1 
ruby-1.9.2-head > RUBY_PLATFORM

Lots of ways to skin the cat.
