SUM is implemented, of course. But sometimes the translation into SQL still yields invalid SQL queries. Turn on logging for SPARQL and check in the marmotta-debug log file. I can also try with my setup.
I would also recommend you to update the latest snapshot of the repository, because there are many bug fixes especially in the SPARQL part.
