Here's what I needed on Debian sid:

git clone https://github.com/mypaint/libmypaint.git
cd libmypaint/
sudo apt-get install scons libjson-c-dev
sudo scons prefix=/usr/local/gimp-git/ enable_gegl=true install

Then configure, make, make install gimp as usual.

To use it (I had to dig around the source to figure it out):
Tools->Paint Tools->MyPaint Brush (or there's a new icon in the
Toolbox), then Windows->Dockable Dialogs->MyPaint Brushes. It shows
a selection of standard MyPaint brushes and they work fine in
monochrome. Pretty cool! I haven't figured out how to get them in
color -- maybe that's not implemented yet.

I tried importing some new brushes and that didn't work:
@Gimp_Official recently retweeted somebody's collection of
neat-looking brushes, so I downloaded them from the link in
https://twitter.com/GisselEscu/status/679981643638161408
and tried installing a few of them in ~/.mypaint/brushes but GIMP can't
load them and doesn't say why, just:
Failed to load data: Error loading [path]/feathersGE.myb

Question for somebody who knows about this new libmypaint dependency:
should we be keeping up to date on libmypaint? In other words, when
I update and build gimp master, I always update and build babl and
gegl first. Should I also update and reinstall libmypaint each time
I update GIMP? Or should we be using a particular tag or branch
of libmypaint?
