I've just tried again, and I'm reproducing the problem.  Using NumPy 

$ PYTHONPATH=.:~/python/numpy/trunk:~/python/numexpr/branches/1.4 python 
PyTables version:  2.3b1.dev
HDF5 version:      1.8.5
NumPy version:     1.5.0.dev
Numexpr version:   1.4.3.dev (not using Intel's VML/MKL)

With the same PyTables binaries, but using NumPy 1.6:

$ PYTHONPATH=.:~/python/numpy/git/numpy:~/python/numexpr/branches/1.4/ 
python tables/tests/test_all.py
Traceback (most recent call last):
  File "tables/tests/test_all.py", line 13, in <module>
    import tables
  File "/home/faltet/PyTables/pytables/trunk/tables/__init__.py", line 
63, in <module>
    from tables.utilsExtension import getPyTablesVersion, getHDF5Version
  File "definitions.pxd", line 138, in init tables.utilsExtension 
ValueError: numpy.dtype has the wrong size, try recompiling

I don't think I'm wrong here, but I'd appreciate if somebody else can 
reproduce this (either with tables or with another Cython-dependent
