And, in fact, RDF::Trine should work just fine without XML::LibXML, you'd just have to force the installation. Removing that dependency (splitting off the rarely used functionality that depends on it) was something I had hoped to get done at the hackathon. It would be nice if core functionality could be had with only pure-perl modules.

I'm fairly confident it's 100% SPARQL 1.0 compliant (it passes all the DAWG tests, anyway). There's initial support for 1.1 things like negation, select expressions, and aggregates. No support yet for sub-selects or SPARQL Update.
