As you know, I am usually on the git side, but since you asked
politely, I branched your 3d_initial_merge to give it a try... ;-)

So I do my usual:
$ bzr clone http://bazaar.launchpad.net/~cirilo-bernardo/kicad/3d_initial_merge
$ cd 3d_initial_merge
$ rm -r build
$ mkdir -p build/release
$ cd build/release
$ cmake 	-DCMAKE_INSTALL_PREFIX=~/SW \
	-DDEFAULT_INSTALL_PATH=~/SW \
	-DKICAD_SKIP_BOOST=ON \
	-DKICAD_SCRIPTING=ON \
	-DKICAD_SCRIPTING_MODULES=ON \
	-DKICAD_SCRIPTING_WXPYTHON=ON \
	../../
$ make -j8
$ make install

... seems to compile fine and gets installed as usual.

An optional:
$ rm -r ~/.config/kicad
made sure, we start from scratch, but without any effect.

$ cd ~/SW/bin
$ PYTHONPATH=~/SW/lib/python2.7/site-packages/ ./kicad

runs kicad, but I get a segfault when I open pcbnew or
the footprint editor by clicking on the buttons.

Let me know if I am sitting on a badly compiled horse or if I should dig
further into the debugging in a debug build...

Setting PYTHONPATH seems unrelated to the segfault.
(Kicad runs with python 3.5.1 at least without complaining
as mentioned ~a week ago.)
