[Gimp-developer] GIMP can't find libmypaint-gegl

[Elle Stone <ellestone ninedegreesbelow com>]

I updated and tried to rebuild GIMP from git, with the following error:

checking for LIBMYPAINTGEGL... no
configure: error: Package requirements (libmypaint-gegl >= 1.1) were not 
met:

No package 'libmypaint-gegl' found

There isn't any libmypaint or libmypaint-gegl in Gentoo portage, and 
installing mypaint from Gentoo portage didn't fix the problem.

I compiled libmypaint from git (https://github.com/mypaint/libmypaint) 
in the prefix with babl/GEGL/GIMP, using the command:

scons prefix=$HOME/data/gimp/gimpdefault/install enable_gegl=true

which put the file "libmypaint-gegl.a" and "libmypaint.a" in the install 
prefix, in the lib folder.

But GIMP still says it can't find libmypaint-gegl. How do I fix this so 
GIMP can compile?
