Stumpwm & using Lisp in guix - particularly quicklisp

[Paul Jewell]

Good morning Guix,

I have a working stumpwm config which I use on my desktop gentoo 
installation, and I want to use the same configuration file under guix. 
Unfortunately I run into a problem as when stumpwm starts, it complains 
it can't find package "ql". Quicklisp is installed in my user home 
directory, but this is clearly not being seen by stumpwm. I also note 
that packages I can install through quicklisp are also packaged in guix 
(e.g. alexandria). When I start sbcl in a terminal, everything works as 
expected, and quicklisp is seen.

This leads me to some questions:

 * How do I configure stumpwm on my system so it looks in my home
   directory, and observes my .sbclrc file when starting?
 * What is the guix recommended way for working with lisp packages?
   Should I avoid using quicklisp, and instead use the provided
   packages in guix? I am unable to find any documentation (either
   official or blog posts etc) explaining this.

Many thanks!
