I see.

I found that the problem is my "ruby" command is ruby-1.9.

I tried "ruby-1.8 bin/mspec ..." but it doesn't help because
bin/mspec invokes mspec/bin/mspec which has
"#!/usr/bin/env ruby" line.  So ruby-1.9 is run anyway.

I need to use rubyspec as follows:

  % ruby-1.8 mspec/bin/mspec -t ruby-1.8.6p111 spec/ruby/1.8

This works.

I investigated why rubyspec doesn't work with ruby-1.9.
It is caused by consume? method:
