Howard,

I'll try to get to you on #gdal today but don't know if I'll have time 
etc. so I send you this by mail too.

First, by the way, many many thanks for diving into this and creating 
the long awaited (by me at least) numpy support in gdal!

Then the problem:
On my pc, probably because it's an amd64 and maybe because I'm running 
python2.5, I get the following error during make install:

Any ideas?

Vincent.
