----------------------------------------
Using RVM we see that ruby fails to compile for 2.0.0. This seems to be fixed in 2.1.0.
Compiling the 2.1.0 as follows succeeds:
rvm --debug install 2.1.0 --without-tcl --without-tk

Trying the same for 2.0.0 fails. With errors logged in the following gist: https://gist.github.com/dajoen/8933735#file-second-attempt-modified-diff-file
