I finally was able to figure out that one too: I was missing the
libgtk2.0-dev package and dependencies. Now it's crystal clear I need
those -dev packages but what was puzzling is that it seemed the whole
compilation process worked but only during the final linking stage it
didn't. And since there was (!) a similar file named
/usr/lib/libgtk-x11-2.0.so.0.2000.1 .

It was necessary for me to compile my own wxruby because the one
installable from gem didn't include opengl for some reason. Maybe it's
the difference in version number, wxruby 2.0.0 vs. 2.0.1:

wxruby-ruby19 (2.0.1 x86-darwin-9 x86-linux x86-mingw32, 2.0.0 x86_64-linux)
