ruby 1.9.2/1.9.3 truck branches fail to build on OS X 10.8
I have attempted building both Ruby 1.9.2 and 1.9.3 from trunk without success. However, I have been able to build Ruby 2.0.0dev successful. Here are the steps that I followed:
$ git clone git://github.com/ruby/ruby.git
$ git co ruby_1_9_3
Next, I'm attaching the error.log from the last step below for reference.
