I was hit by this error too today. The error occurs with Python2.6
because it introduces a new module msvc9compiler.py that somehow
breaks detecting mingw compiler. In general (and out of topic),
the error may occur  when executing

  python setup.py build_ext --compiler=mingw32

As a workaround, one should use build command before build_ext:

  python setup.py build --compiler=mingw32

Try using
  python f2py.py -c --compiler=mingw32 -m hello hello.f90

Note that `-c` option has different meaning in f2py.py.
