One would certainly have thought so ... :-)

That nailed it. It was importing _imaging.pyd from C:\Python23\DLLs, and 
there was also an _imagingft.pyd in there - I hadn't realized those 
files were in the PIL directory (duuuh). Deleting the DLLs copies fixed 
the problem (though I can't help wondering what I might have broken).

Thanks for your help. My code is now properly portable again.
