Oh, get well soon, then.

Ah, ok. There was only a symlink installed 
in /usr/lib64/ruby/site_ruby/1.8/x86_64, but not the whole library. After 
copying the library over from the build directory, it worked fine. Seems like 
there is a mistake in one of the CMake files since only a symlink is 
installed.
