Na, you can change it:

 >> $: << "search_here_last
"
=> ["/usr/local/lib/ruby/site_ruby/1.8", "/usr/local/lib/ruby/ 
site_ruby/1.8/i686-darwin8.5.2", "/usr/local/lib/ruby/site_ruby", "/ 
usr/local/lib/ruby/1.8", "/usr/local/lib/ruby/1.8/i686-darwin8.5.2",  
".", "search_here_last\n"]
 >> exit
Firefly:~$ irb
 >> $: << "search_here_last"
=> ["/usr/local/lib/ruby/site_ruby/1.8", "/usr/local/lib/ruby/ 
site_ruby/1.8/i686-darwin8.5.2", "/usr/local/lib/ruby/site_ruby", "/ 
usr/local/lib/ruby/1.8", "/usr/local/lib/ruby/1.8/i686-darwin8.5.2",  
".", "search_here_last"]
 >> $:.unshift("search_here_first")
=> ["search_here_first", "/usr/local/lib/ruby/site_ruby/1.8", "/usr/
