My bad, I posted the wrong log file in the post. I actually ran rake as 
as sudo, and didn't get that error, but another one which said that I 
was missing -lGL, which appears to be an OpenGL library.

FYI, when running Yoshi's extconf.rb, I get a similar notification about 
missing -lGl and some other libraries. Any OpenGl users familiar with 
this library, and how to get it?
