>Description:
wxcairo package from x11/py-wxpython fails to load.
Attached patch fixes the problem for me. I'm not sure this is the "ultimate" 
fix, but I can't come up with something else :)

See http://mail-index.netbsd.org/tech-pkg/2012/02/20/msg008552.html for some 
more details.

>How-To-Repeat:
python2.6 -c 'import wx.lib.wxcairo'
