hi
There is no point rebuilding MyPaint or trying different versions. It won't
work if your pygtk doesn't have numpy support. It's pygtk that you have to
replace or rebuild, or figure out how to make MyPaint actually use the right
version.
You can do the following test on commandline to check whether your pygtk has
numpy support:
martin ~$ python
Python 2.7.2+ (default, Jan 20 2012, 17:51:10)
[GCC 4.6.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gtk
>>> pixbuf = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB, False, 8, 3, 3)
>>> pixbuf.get_pixels_array()
array([[[ 64, 217, 130],
[ 1, 0, 0],
[ 0, 0, 0]],
[[106, 1, 0],
[106, 3, 0],
[101, 4, 0]],
[[100, 1, 0],
[100, 1, 0],
[131, 5, 0]]], dtype=uint8)
>>>
You can also try to start mypaint with a different python version (which may
end up using a different pygtk version) with "python2.6 /path/to/mypaint" or
similar.

Martin
