I just found out that the problem is in blitz_spec.py on line 88:

class array_converter(standard_array_spec.array_converter):
     def init_info(self):
         standard_array_spec.array_converter.init_info(self)
         blitz_headers = ['"blitz/array.h"',
                          '"%s/arrayobject.h"' % nx.NX_ARRAYPKG,
                           '<complex>','<math.h>']

nx.NX_ARRAYPKG cannot be evaluated:

AttributeError: _TypeNamespace instance has no attribute 'NX_ARRAYPKG'

I replaced %s by 'Numeric' and it works.
