Re: linkeddata gem dependency missing

Looks like Syck get's used as part of RDF::RDFa development dependencies. It's used by YAML. YAML and Syck are (were) part of the Ruby standard library, so wouldn't be installed separately. It might be there because of RDF::RDFa's use of YAML, as I found it in a 0.3.5 version gemspec file (but can't actually find it in any installed specifications.

The gemspec implementation was re-done in RDF::RDFa version 0.3.5.1 due to some other dependency issues in some 1.8 implementations. You might try dong 'gem update rdf-rdfa' and see if that fixes the issue. The required version in the linkeddata gem hasn't changed in a while, so it won't happen automatically.

If the problem persists, please send the ruby version you're using. If, for some reason, you are using 1.8 gemspecs with a 1.9 version of Ruby, this might be a source of the problem. In any case, it should not exist with version 0.3.5.1 of RDF::RDFa.
