I don't know if it's still actual for you Ethan but I've got the same 
error today trying to install rqr gem with latest ruby(1.9.2dev). This 
error happens during try_cpp function and it gave me a clue that 
something is wrong with my C++ compiler. Despite the fact that cpp was 
installed I still got the error and tried to install g++ using apt-get 
(i have ubuntu 10.04). Surprisely it works.

Hope this helped
