Anyone using the MetaWeblog API?

Has anyone on the list managed to get the Radiant MetaWeblog API plug-
in to work?

I’ve been trying to use it, but have been unsuccessful so far. I keep
getting a “NoMethodError”. It seems like I’m missing some dependency,
but I can’t figure out what it is. I’ve posted an issue on the
author’s google code svn site, but no response, so far.

Best regards,
