Как собрать directfb из сорцов на убунте ?

#apt-get install build-essential

configure: error: 
*** DirectFB compilation requires fluxcomp ***

Unless you are compiling from a distributed tarball you need fluxcomp
available from git://git.directfb.org/git/directfb/core/flux installed
in your PATH.

sudo apt-get build-dep directfb

mkdir directfb-build && cd directfb-build
apt-get -b source directfb

mkdir dfb_{build,install}/
cd dfb_build/
git clone https://github.com/DirectFB/directfb --depth=1 -b master
sed -i '/#include <string>/a #include <functional>' directfb/lib/direct/Base.h
git clone https://github.com/Distrotech/flux --depth=1 -b master
cd flux/
./autogen.sh
./configure
make -j4
cd ../directfb/
PATH=`pwd`/../flux/src:$PATH ./autogen.sh
PATH=`pwd`/../flux/src:$PATH ./configure
make -j4
make DESTDIR=`pwd`/../../dfb_install/ install
