 Hi,
  I am currently running python 2.7.2 compiled using the C compiler GCC
 4.2.1 Compatible Apple Clang 3.0 (tags/Apple/clang-211.10.1) and fortran
 compiler gfortran on a new MacBook Pro with Mac OSX 10.7 (Lion). I
 successfully installed numpy 2.0.0.dev-7297785 from the git archive.
 However, when trying to import another python package (Atpy) it fails
 with:

 invalid[np.int64] = -np.int64(2**63-1)
 OverflowError: Python int too large to convert to C long

 After a short test, I've found that the error comes from simply trying:

 % numpy.int64(2**63-1)

 However, if you try:

 % numpy.int(2**63-1)

 The error does not occur. This same error occurred under the latest stable
 release (1.6.2)
