I was trying with mingw32 via cygwin with gcc 2.4.4,
which also failed with a cryptic error:

    Directories to search for the libraries can be specified in the
    numpy/distutils/site.cfg file (section [lapack]) or by setting
    the LAPACK environment variable.
  warnings.warn(LapackNotFoundError.__doc__)

I am updating cygwin to see if anything changes...
