Yeah it is ;). But as Sage moves away from it more dev oriented
clientel this ought to be handled better. I have made this
http://trac.sagemath.org/sage_trac/ticket/5260
and I think the Sage should even check for the existence of an
appropriate compiler if possible and error out sensibly when no
compiler is available. This might be trickier for f2py, weave and
ctypes, but we will do our best to get this fixed and might even
complain upstream about the problem.
