Jeff,
Thanks. That indeed did work (after downloading python-dev package). I just
didn't know that 'install' was the argument that I was supposed to pass to
it =)
After installing I tried griddata again. My input data was originally a
list. The new griddata didn't like this and so I simply used
a=array(thelist) to convert to an array and tried again. It took quite a
bit longer than the old griddata, but the resulting output now looks
correct! Better a slow and correct answer than a fast and garbage one.
Thanks again Jeff (and thanks for the new griddata if you are the one that
made it)!
