Replace it with 'handle'.  I've checked into the main, 1.0, and x.9 
branches (in case we do another 0.9.x release) a fix that does that.

Or, alternatively, replace your version of the DAG libraries with a 
newer version, and recompile.  That code is compiled only if 
HAVE_DAG_STREAMS_API isn't defined, which I think is the case only in 
older versions of the DAG libraries.
