sudo apt-get install git
git clone git://github.com/xbmc/xbmc.git
then install necessary dependencies
sudo apt-get install git-core build-essential gawk pmount libtool nasm yasm automake cmake gperf zip unzip bison libsdl-dev libsdl-image1.2-dev libsdl-gfx1.2-dev libsdl-mixer1.2-dev libfribidi-dev liblzo2-dev libfreetype6-dev libsqlite3-dev libogg-dev libasound2-dev python-sqlite libglew-dev libcurl3 libcurl4-gnutls-dev libxrandr-dev libxrender-dev libmad0-dev libogg-dev libvorbisenc2 libsmbclient-dev libmysqlclient-dev libpcre3-dev libdbus-1-dev libhal-dev libhal-storage-dev libjasper-dev libfontconfig-dev libbz2-dev libboost-dev libenca-dev libxt-dev libxmu-dev libpng-dev libjpeg-dev libpulse-dev mesa-utils libcdio-dev libsamplerate-dev libmpeg3-dev libflac-dev libiso9660-dev libass-dev libssl-dev fp-compiler gdc libmpeg2-4-dev libmicrohttpd-dev libmodplug-dev libssh-dev gettext cvs python-dev libyajl-dev libboost-thread-dev libplist-dev libusb-dev libudev-dev libtinyxml-dev libcap-dev curl swig default-jre autopoint libltdl-dev libtag1-dev
install more dependencies
sudo apt-get build-dep xbmc
finally bootstrap, configure, compile and install
sudo make install
