+NumPy needs a C compiler, and for development versions also needs Cython.  A Fortran
 compiler isn't needed to build NumPy itself; the ``numpy.f2py`` tests will be
 skipped when running the test suite if no Fortran compiler is available.  For
 building Scipy a Fortran compiler is needed though, so we include some details
