Comment(by sienkiew):

 As far as I can tell, python 2.5 does not always have ctypes:

 Mac OSX 10.5:
 {{{

 Solaris 8:

 }}}

 It seems to work in python 2.5 on linux and python 2.6 on linux and mac.

 These are all python interpreters that I compiled from source, but I did
 not make any special effort to include/exclude ctypes.  The auto config
 must have done it, or it must be built-in to python.

 It is worth considering whether numpy should be dependent on "standard"
 libraries that may not be present.

 On my machines that do not have ctypes, this is the only test that is
 reporting a problem.  That suggests that any other test that requires
 ctypes is automatically skipped.
