[ibr-dtn] ibr-dtn and ubuntu

hai .. I am very exciting with ibr-dtn, but I never could install ibrdtnd and ibrdtn-tools like the ones in " http://trac.ibr.cs.tu-bs.de/project-cm-2012-ibrdtn/wiki/download", I've tried on ubuntu 12:04 and 13:04, but still can not even though I've also tried to use the way like in " http://trac.ibr.cs.tu-bs.de/project-cm-2012-ibrdtn/wiki/source". maybe you can help me, because this is also for my college final exams .. thank you. Regards evan.
