Hunchentoot development has picked up after a lengthy hiatus, and some of the recent changes have affected other projects. For the most part, projects have been adapted to work, but there's a big exception: Weblocks.
Weblocks does not build with Hunchentoot 1.2.2 because it references hunchentoot:*default-handler*, which doesn't exist any more. I reported the problem on the mailing list, but haven't gotten a response yet.
Do you use Weblocks? Can you help adapt it to the new Hunchentoot? If it isn't updated sometime soon, I won't be able to include it in Quicklisp in the future. (You can always go back in time, if you have to.)
