One of the most annoying parts of ASDF is all the GPG verification that needs to happen. This is not my favourite thing to do, let me tell you.
Fortunately, Ubuntu 7.10 takes some of the pain away. To install Weblocks dependencies, you can do:
$ sudo apt-get install cl-closer-mop \
Then in the REPL:
(asdf-install:install :cl-json :tinaa :cl-cont :fare-matcher)
Then follow the instructions on installing Weblocks for getting Weblocks itself. Does someone know some easy way to verify the GPG keys besides hunting for the keys?
Update: mathrick on #lisp says "press 0". LOL!
