 Happens on

  - Mac OSX Leopard, 32 bit python 2.5.4

  - Solaris 8, 32 bit Python 2.5.4

 Not on

  - Red Hat Enterprise 4 Linux, 32 or 64 bit python 2.5

  - Red Hat Enterprise 5 linux, 32 bit python 2.5

 When you compile python, it automatically decides whether to include
 ctypes.  In my experience, it likes Linux but not Mac or Solaris.

 It is not clear to me if this means that the test should be changed (e.g.
 to skip if ctypes is not available) or if ctypes should become a hard and
 fast requirement to run numpy.
