Hi Josh,

it seems wx uses color with a "u" and the compatibility layer that wraps colour as color is not present for you. Try changing this to Colour and if it works send the patch. That should work as a general solution.

Yes, I just discovered this. 

Here is the patch:

diff --git a/gr-wxgui/src/python/plotter/gltext.py b/gr-wxgui/src/python/plotter/gltext.py

Once I changed this to wx.Colour, it didn't show the previous error. how ever, now I get something related to the OpenGL rendering context:
