No problem at all.

scipy 0.8.0 has one issue with python 2.7. You should either use the 0.8.x
svn branch or 0.9.0b1 from svn or Sourceforge.

This is OK.

This is incorrect. When you build with distutils, CFLAGS/FFLAGS will
overwrite all flags, not append them. You should just leave this out,
default flags work fine with numpy 1.5.1 + scipy as specified above.

Looks OK. As a sanity check, run numpy.test('full'). There are some extra
distutils tests that get run like that.

That looks like you have some other numpy install hanging around.

Any ideas?
