Rails fails in JRuby out of box on Mac OS X (with Stack Trace)

gistfile1.txt

My first attempts at running a new Rails application on JRuby is completely failing.  Through the process of elimination, I have traced the source of the problem down to the asset pipeline in Rails 3.2.  Though I do not know how to fix this:

   stat.st_gid unsupported or native support failed to load
   org/jruby/RubyFileStat.java:432:in `gid'

This is on October 20, 2012.  Using jruby 1.6.7 and Rails 3.2.8 out of the box with the gems as published on this date.

Here are the steps to reproduce - again, no custom code on my part.

Using Mac OS X Mountain Lion, I installed the following:

JDK 1.7 from http://www.oracle.com/technetwork/java/javase/downloads/jdk7u9-downloads-1859576.html

Specify that 1.9 is preferred with the environment variable:

   export JRUBY_OPTS=--1.9

JRuby 1.6.7 using rvm with the command:

   rvm install jruby

Switch to using jruby with:

   rvm use jruby

Install the Rails gem:

   gem install rails

Create a new, completely virgin Rails project:

   rails new throw_away_sample

Move into the directory and run the bundle and migrate the initial database:

   cd throw_away_sample
   bundle
   rake db:migrate
   
Now running "rake assets:precompile --trace" results in

   rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets --trace
** Invoke assets:precompile:all (first_time)
** Execute assets:precompile:all
** Invoke assets:precompile:primary (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
** Invoke tmp:cache:clear (first_time)
** Execute tmp:cache:clear
** Execute assets:precompile:primary

Fixed by deleting the following line from my .bashrc file:
