Please reread, including comments in the linked github post. 1.9.3 does compile with clang, but ruby's own test suite ('make test' in the ruby build dir) does not pass.
Also, if you had 4.1 then upgraded to 4.2 you may still have 4.1 gcc around.
Remember that after downloading Xcode form App Store you actually have to INSTALL it and after RUN IT at least once so everything works properly.
