MyPaint doesn't run anymore.

[neukomp@…]

I tried to run MyPaint again today. I haven't needed it for some months.

It wouldn't start. So I tried if from the command line and got this error string:

I'm not sure if this a MyPaint, pygtk or python error.

RuntimeError: pygtk was not compiled with Numeric Python support

When Googling this error I found ​this helpful page which made it clear that this will happen if py-gtk is compiled without py-numpy installed, and I can verify that on my system. So we just need to add a py-numpy dependency to py-gtk and rebuild. Done in r. Wait 30 minutes, then run "sudo port selfupdate" and "sudo port upgrade outdated" as usual.
