OK, thanks. I don't really know why it's failing, but I'm going to continue trying to get other backends installed to test them.
I also now have independent reasons not to use the MacOSX backend: Thu Jul 2 14:51:48 Python-64[56094] <Error>: CGContextSetLineDash: invalid dash array: negative lengths are not allowed. I can't draw dashed lines.
