you have to install all four debs and the dependencies in each of them. easiest way to do this is to download them to a dir, and do

dpkg -i *.deb
apt-get -f install

note that this was the minimal set of dependencies i could get it to work with, using the precompiled binary packages in ubuntu, not a sensible compilation targetting harmattan. still, it works fine and installs without dependency issues for me.
