I'm one of the leaders of OpenCog, and I can tell you that these accusations are spurious and bizzare. Regarding installing dependencies and compiling the code, detailed instructions are provided on our wiki. All the major features have been released (as they were ported/cleaned up during 2008 and 2009).
Some interesting features were previously implemented in Novamente but during rushed commercial contracts, in a hacky way that means it's easier to re-implement them now. Sometimes people have difficulties compiling the code, but we help them if they show up on IRC (I don't remember Louie though).
I'm in Hong Kong for the OpenCog-related project here (http://opencog.org/2010/10/opencog-based-game-characters-at-hong-kong-poly-u/). I'm a "transplanted Westerner", originally from New Zealand (moved here about 2 months ago). Available basically any evening.
As in "extraordinary claims demand extraordinary evidence".
A summary of the evidence can be found on Ben's blog
Adding some more info... Basically the evidence can be divided into two parts. 1) Evidence that the OpenCog design (or something reasonably similar) would be a successful AGI system when fully implemented and tested. 2) Evidence that the OpenCog design can be implemented and tested within a decade.
1) The OpenCog design has been described in considerable detail in various publications (formal or otherwise); see http://opencog.org/research... (read more)
