I think it's related to the previously announced change to raptor:

"Future API change: From the next release of Raptor, raptor_statement
predicates will return identifiers of type
RAPTOR_IDENTIFIER_TYPE_RESOURCE instead of
RAPTOR_IDENTIFIER_TYPE_PREDICATE."

Make sure that the raptor (and rasqal) sources are all up to date with
respect to SVN.  That means three directories if you followed the
configuration given at http://librdf.org/INSTALL.html

The latest svn revision 10705 works with the API change.  [Apart from 1
thing in rdf/xml-abbrev serializing that I have yet to fix].
