Hunchentoot and postmodern on sbcl or clozure. Use clbuild primarily, asdf-install is fine, but typically you just manually download the fringe packages that aren't supported by clbuild (same as in CPAN, pear, YUM, apt or whatever.)
The continuation based web frameworks are not for mere mortals.
Rucksack is a toy, not a datastore. Use Postmodern which rolls an ORM over Postgres. CLSQL is quirky.
Good luck. Ask in #lisp.
Thanks for the tips. I haven't checked out Postmodern. I'll check that out and try building up something with that stack.
