It looks like you need some additional libraries that wRuby depends on. 
Since Linux systems vary so widely, it's sometimes necessary to install 
some additional dependencies to get wxRuby to work.

The missing library is libGL.so and I think on Debian-type systems you 
need to install a package called something like "libgl1-mesa" to get 
this. Searching for "mesa" should turn it up.
