This error was in JRuby's yaml parsing and has been fixed as of r5344.

So I can download or build the mongrel gem manually and install it using JRuby.

However trying to do a gem install from the rubgems repository still doesn't process the platform correctly and fails trying to build fastthread (which should only be built on MRI).

I don't know yet whether the problem is with:

* jruby's slightly patched version of gems 1.0.0
* the mongrel gem itself
* ???
