Problem building Io with the addons

having a hell of a time with addons!!

This site:

http://jetpackweb.com/blog/2011/02/08/io-language-addons-and-making-them-work-in-ubuntu/

explained that a bunch of dependencies were required before the
addons would be configured for installation. Got them loaded up!!
The build choked here:

I think that I don't have a dependency issue:

sudo apt-get install libyajl-dev

libyajl-dev is already the newest version.
