testbot jruby compatability

[jesg]

How do I run a test on jruby?

I've tried the following:

1. Install the testbot
   [jason@arch ~]$ rvm use jruby
   Using /home/jason/.rvm/gems/jruby-1.7.11
   [jason@arch ~]$ export JRUBY_OPTS="--1.9 -Xcext.enabled=true"
   [jason@arch ~]$ gem install testbot
   Building native extensions. This could take a while...
   ERROR: Error installing testbot:
   ERROR: Failed to build gem native extension.

/home/jason/.rvm/rubies/jruby-1.7.11/bin/jruby extconf.rb

/home/jason/.rvm/rubies/jruby-1.7.11/lib/ruby/shared/mkmf.rb:14: Use RbConfig instead of obsolete and deprecated Config.
mkmf.rb can't find header files for ruby at /home/jason/.rvm/rubies/jruby-1.7.11/lib/native/include/ruby/ruby.h

extconf failed, uncaught signal 1

Gem files will remain installed in /home/jason/.rvm/gems/jruby-1.7.11/gems/posix-spawn-0.3.8 for inspection.
Results logged to /home/jason/.rvm/gems/jruby-1.7.11/extensions/universal-java-1.7/1.9/posix-spawn-0.3.8/gem_make.out

2. Set the 'USE_JRUBY' environmental variable in ~/.bashrc to true and run the testbot server and testbot runner on ruby 1.9.3. Also I have installed jruby on my system.

Running the example program in the README gave the following error.
[jason@arch testbotdemo]$ testbot --test --connect localhost
