Hi Arto, Looks like they are running Debian Lenny on Bamboo: http://docs.heroku.com/bamboo http://bamboo-ree-versions.heroku.com/ Debian package information for Lenny (1.4.17-1): http://packages.debian.org/lenny/libraptor1 Are you currently investigating adding support for 1.4.17? Although I am spoilt for choice now, with Gregg releasing writer support in his rdf-rdfxml gem :) nick. -- You received this message because you are subscribed to the Google Groups "Heroku" group.
