I thought I'd try that out on Debian.  Using current (from the 
respective git repositories this morning) gnustep and oolite code, I 
built with gcc and with clang.

On my system in the tutorial the gcc version was reporting a frame rate 
in the 70s.  Unfortunately, the clang version crashed after displaying 
the startup screen, with an assertion checking that an object was a ship:
