Yes, I am.

I just updated from svn; test_regression looks good. Unfortunately, I need to 
report a new error:

======================================================================
ERROR: check_singleton (numpy.lib.tests.test_getlimits.test_longdouble)
----------------------------------------------------------------------

Here's what I get:

numpy.intp('0xffffffffffffffff',16)
---------------------------------------------------------------------------
exceptions.OverflowError                             Traceback (most recent 
call last)

OverflowError: long int too large to convert to int
