Based on comments in https://aur.archlinux.org/packages/gegl-git/, it 
does look like maybe the original problem was that GIMP was finding a 
too-outdated version of GEGL.

I never needed to export GIO_EXTRA_MODULES until I tried to run GIMP 2.8 
installed from the Gentoo package manager alongside babl/GEGL/GIMP from 
git installed in a prefix. But here's the reference, fwiw:

Looking at what Mitch said, it seems exporting GIO_EXTRA_MODULES is only 
be needed if glib is also built in the prefix. So sorry for the noise! 
if you didn't also build glib in the prefix.

For the next person trying to build GIMP from git who might stumble over 
this thread, a few other "why it doesn't work and what to do" are 
documented here:
