When I'm on Debian, using Guix as package mánager, I found often in the need to configure Emacs with the full path to a program. By example, SCBL and Sly. I need to customize the inferior lisp variable and I can't figure out the way to give the config file the full path to the SCBL 'executable'. So Sly doesn't find SCBL.
Also, outside Emacs situation, I installed Hplip from Guix because the debian version was giving me problems and I can't run the new installed hplip as I wish. Maybe this two situations are solvable with another perspective. Rhat isn't what I'm looking after. I only wonder now... Is there a canonical way to retrieve the full path in my profile to a specific package with a command, in Guix on a foreign distro? I used locate or find, but I can't figure out from the output how to detect and select the correct one.
