I'm looking at the source for blit_array, and I guess this error makes
sense. Blit_array is only dealing with 8bit, 16bit, and 32bit array data
types. It should be ease to add support for 64bit numbers as well, since
this is what Numeric seems to be building by default.
I've just committed some 64bit support to blit_array. It's in CVS but I
don't know how easy it would be for you to test. It seems like it should
just work.
Still, the 64bit arrays are going to take twice the needed memory as the
32bit ones.
