redland-bindings cannot be rebuild against perl 5.20. The file perl/CORE_wrap.c which is provided by upstream does not work for new perl. The file was generated by old swig and is part of tarball. If the file is generated with new swig it will works. It can be easily fixed at spec file, same was as PHP wraper. Just add a following command in %prep section rm -f perl/CORE_wrap.c The wrapper will be regenerated.
