Typegen fails with typelib/orogen/utilrb/metaruby master

Hi all,

I'm currently testing the typelib/orogen/utilrb/metaruby master combo
on my Ubuntu 12.04 system with ruby 1.9.3 (which is actually 1.9.1:
http://packages.ubuntu.com/precise/ruby1.9.3)

I merged the latest master branches into the toolchain-2.7 branches.

When calling typegen I get the following error output:

typegen -iorocos-kdl -o /tmp/foo test RobotState.hpp
/home/rsmits/orocos_ws/install_isolated/lib/ruby/1.9.1/x86_64-linux/orogen/gen/typekit.rb:844:
