[cfe-users] can't find binary/executable

[Michael Mitchell via cfe-users]

Problems been solved. For anyone else with the same question, the problem
was that I wasn't using the clang that I had built the file against (clang
came installed by default on the system). When I ran ./build/bin/clang and
followed the instructions at this tutorial it worked fine
