It sort of sounds like GIMP isn't finding a recent enough version of 
GEGL. Did you install babl from git and GEGL from git in the same prefix 
as GIMP from git?

In case they might be helpful, I put up some articles on building and 
updating GIMP from git:

Building GIMP for artists and photographers

Updating GIMP for artists and photographers

The second article also explains how to use the git log to see the 
latest updates.
