This is caused by ruby1.8 forcing the use of gcc-4.6 and linking against
a C++ library. Adding a build-dep on libstdc++6-4.6-dev (or g++-4.6)
fixes the problem.

I was thinking of fixing this directly in the git repo, but apparently
that is messed up and doesn't contain the commits leading to 6.0.3-1. A
(trivial) patch is attached anyhow.
