I finally gave up on my hostmonster admins. They told me they were seeing possible in the future to install git but whatever it is not now. So i tried to tackle the problem from my side, SparkleShare generates paths like ~/SparkleShare/subfolder/.git or at least that was what I was told by hbons the manager. But even creating those directories and adding config files to those .git/ subdirectories the thing would not work for sourcing the remote path of the user space installed git. This is really a shame so project cancelled.
