FYI: I'm getting an rdoc error installing buildr in trunk JRuby (r6633), Installing on MRI in MacOS 10.5.2 works fine:
$ jruby -S gem install buildr Bulk updating Gem source index for: http://gems.rubyforge.org/ Updating metadata for 3 gems from http://gems.rubyforge.org/ ... complete Successfully installed net-ssh-1.1.4 Successfully installed buildr-1.3.0-java 2 gems installed Installing ri documentation for net-ssh-1.1.4... Installing ri documentation for buildr-1.3.0-java... RDoc failure in lib/java/nailgun.rb at or around line 237 column 40 Before reporting this, could you check that the file you're documenting compiles cleanly--RDoc is not a full Ruby parser, and gets confused easily if fed invalid programs. The internal error was: ERROR: While executing gem ... (NoMethodError) undefined method `add_require' for nil:NilClass
