Jruby Gem Build fail

[JoshMcKin]

I was trying out jruby and threading goodness by branching an existing project but ran into an issue installing the latest simple_record gem:

/Users/joshmckin/.rvm/rubies/jruby-1.6.0/bin/jruby extconf.rb
WARNING: JRuby does not support native extensions or the `mkmf' library very well.
Check http://kenai.com/projects/jruby/pages/Home for alternatives.
mkmf.rb can't find header files for ruby at /Users/joshmckin/.rvm/rubies/jruby-1.6.0/lib/native/include/ruby/ruby.h

Gem files will remain installed in /Users/joshmckin/.rvm/gems/jruby-1.6.0/gems/escape_utils-0.2.3 for inspection.

According to the bug below escape_utils has not plans to build a jruby/java extenion. Would i be possible to make use of anther gem? brianmario/escape_utils#7

I was able to install version simple_record-2.0.5.
