This is one solution that works. The other one is to use NumPy  
instead of Numeric.

There are two combinations that are known not to work:

1) Python 2.5/2.6 + Numeric on 64-bit machines. The causes are known  
but no one is going to fix Numeric any more.
2) Numeric 24.x with MMTK. The exact reason remains unclear but  
enough people have reported problems to suggest that this is not a  
good combination.

BTW, I have released ScientificPython 2.8 a few days ago, which uses  
NumPy by default, but can still be installed for Numeric if  
necessary. MMTK will use whatever ScientificPython uses. However, all  
my development machines use NumPy now, so Numeric support might  
become less reliable for lack of testing in the future.
