Type 1 is RAPTOR_IDENTIFIER_TYPE_RESOURCE.  Older code only expects
type 2 RAPTOR_IDENTIFIER_TYPE_PREDICATE.

I *thought* I changed all the redland 1.0.3 code to expect both, and I
just checked the source in SVN (rdf_parser_raptor.c is where this error
message comes from) and it seems I missed the case in 1.0.3

If you were using 1.0.3 tarballs you'll need to edit rdf_parser_raptor.c
around line 194 to allow both types.  From:
  } else if (rstatement->predicate_type ==
RAPTOR_IDENTIFIER_TYPE_PREDICATE) {

to
  } else if (rstatement->predicate_type ==
RAPTOR_IDENTIFIER_TYPE_RESOURCE ||
             rstatement->predicate_type ==
RAPTOR_IDENTIFIER_TYPE_PREDICATE) {

However, this *is* fixed in SVN so I'm guessing you have some 1.0.3 or
older shared library being used.

did you delete shared libraries?  You can automate that with:
  sudo make uninstall
inside the packages.

Try ldd ./example2 and see what shared library it is using.
