So! Mostly I phosted an example of Shinmera's tooter, 
the official mastodon CL package (activitypub client
2 server). I also tarred up a bunch of dependencies
including my own eve-quine.

tooter is based on Weitz' DRAKMA for requests and so
has lots of deps.

I think deps.tar can be used like this:
tar xvf deps.tar
mkdir ~/common-lisp

ecl <<EOF
(require :asdf)
(let ((files (directory #p"deps/")))
 (loop initially (uiop:chdir #p"~/common-lisp/")
  for tgz in files
  do (uiop:run-program
      (format nil "tar xzvf ~a" (namestring tgz)))))
EOF

And then you could 
$ ecl -load do-tooter.lisp
which you can also find in my gopherhole.
