I think the problem is that you have compiled the PyTables extensions using an old version of Pyrex. Try installing the lastest version of Pyrex and see if it goes better (remember to re-generate the C-files; 'touch src/*.pyx' will do the trick). In any case, it is known that numarray has problems when working with 64-bit platforms and Python2.5, so upgrading to PyTables 2.0 (with NumPy at its core) is strongly recommended.
