Greetings,

For some reason which I have been unable to track down [tryruby.org](http://tryruby.org) is  
down again.

What makes almost no sense is the error log is stating:

How earth would tryruby.rb be unable to find ruby\_parser, when if i  
drop into irb and require ‘ruby\_parser’  
it returns true?

I don’t recall changing a single thing relevant to ruby1.9 on the  
server. I have also tried just dropping in ruby\_parser’s code into  
tryruby, but no avail.

This really makes no sense why it would all of a sudden stop pulling  
in ruby\_parser.

Different environments? Maybe it helps if you dump the current  
environment at the start of your CGI script - at least temporary for  
debugging purposes.
