Ivan has been doing some great work on the Mono/IronRuby continuous integration server recently. He and Ankit got xbuild support integrated, and now we have new tarballs being generated for each build. You can find them here:

I’ll be using these tarballs as the ‘upstream’ source for the upcoming debian packages of IronRuby. I filed ITP for IR last year and haven’t gotten around to making it happen until now. Sorry world.
