Looks like I should have tried earlier.  On Friday I was able to build MLT
from subversion.  Testing it out now has solved the export problem (by
replacing kdenlive_renderer with inigo in the export.sh script, which I
tried previously but to no effect).  So now my only problem is to get a
recent checkout of kdenlive to work, so that I can also edit.
