Summary:                    example.py: "librdf_query_execute(" ... syntax
error, unexpected '(', expecting '{'
Description: 
I built redland 1.0.16 from source, and the Python bindings.  Running example.py
isn't working:

# python example.py
found statement: <http://www.dajobe.org/>
<http://purl.org/dc/elements/1.1/creator> "Dave Beckett"
Parsing URI (file) ../data/dc.rdf
Parsing added 3 statements

Querying for dc:titles:
Traceback (most recent call last):
  File "example.py", line 71, in <module>
    for result in q.execute(model):
  File "/root/redland-1.0.16/redland-bindings-1.0.16.1/python/RDF.py", line
1995, in execute
    results = Redland.librdf_query_execute(self._query,model._model)
RDF.RedlandError: "syntax error, unexpected '(', expecting '{'"

-----

I went into example.py and tweaked line 69 from
    q = RDF.Query("SELECT ?a ?c WHERE (?a dc:title ?c) USING dc FOR
<http://purl.org/dc/elements/1.1/>")
to
    q = RDF.Query("SELECT ?a ?c WHERE {?a dc:title ?c} USING dc FOR
<http://purl.org/dc/elements/1.1/>")
and seemed to get past that (/{ error, but then hit another error:

Querying for dc:titles:
librdf error & - syntax error, unexpected $end
Traceback (most recent call last):
  File "example.py", line 71, in <module>
    for result in q.execute(model):
  File "/root/redland-1.0.16/redland-bindings-1.0.16.1/python/RDF.py", line
1995, in execute
    results = Redland.librdf_query_execute(self._query,model._model)
RDF.RedlandError: 'The namespace prefix in "dc:title" was not declared.'

-----

`make check` of the bindings seems fine.  I did have some failures in the `make
check` of the raptor2 and redland.  I've attached that output to this email, in
case it's relevant.
