possible to fetch sources from git repository?

Hi, on the GCompris mailing list Yeves Combe announced that he has not only compiled GCompris on Mac OS X but also has used the gtk+ aqua port. It shoud be possible to provide some portfiles to make these results available to mapcports. Some of the sources are only available in git repositories so the question arise whether it is possible to fetch sources from git repositories? The man page only mentions cvs repositories. Gruss Olaf
