When trying to build it from source, I have to install McCLIM, but using the McCLIM install guide:

* (ql:quickload "mcclim")

debugger invoked on a SB-INT:SIMPLE-READER-PACKAGE-ERROR in thread
#<THREAD tid=154503 "main thread" RUNNING {10045100A3}>:
  Package QL does not exist.

Do you have a more detailed install guide than what’s in readme.org?

When running the prebuilt:

debugger invoked on a SB-EXT:FILE-DOES-NOT-EXIST in thread
#<THREAD "main thread" RUNNING {10041C8003}>:
  The file
  #P"/home/j86585o3/common-lisp/cl-dejavu-20210124-git/dejavu-fonts-ttf-2.37/ttf/DejaVuSans.ttf"
  does not exist:
    No such file or directory

Cadence thanks for your two great problems! In reverse order if I may.

2. If this is bizarre and terrible hardcoded path really the only problem, my punt is to 

mkdir -p /home/j86585o3/common-lisp/
cd /home/j86585o3/common-lisp/
git clone https://codeberg.org/TurtleWare/cl-dejavu

though I would encourage you to build it yourself!

1. You can very easily install quicklisp as outlined here: https://www.quicklisp.org/beta/. Basically roll your eyes a bit at it being called a beta. One more decade...

https://www.quicklisp.org/beta/

The short and guided installation should end up with basically

(load "~/quicklisp/setup.lisp")

in your ~/.sbclrc file. (sbcl init file), assuming you installed it accepting the defaults.

1b. As referenced by the McCLIM developer JackDaniel here https://functional.cafe/@jackdaniel/112484865422197566 about this, you should manually acquire Xach's (of quicklisp.org) https://github.com/xach/zpb-ttf, similarly to cl-dejavu above (non-github download: https://xach.com/lisp/zpb-ttf/).

Please report back in!
