Use of local-file in icecat-source definition breaks REPL |

CC: Mark H Weaver, one of the Icecat maintainer.
Hello,
The problem is that local-file doesn't work in Geiser. This breaks
working at the REPL:
Enter `,help' for help.
scheme@(guile-user)> ,m (gnu packages linux)
While executing meta-command:
ERROR:
1. &formatted-message:
format: "~a: patch not found\n"
arguments: ("icecat-use-older-reveal-hidden-html.patch")
Any ideas of what could be done about it?

Thanks for Christopher Baines on #guix who pointed that local-file
seemed to behave correctly at the REPL and Geiser (indeed!). It made me
try to reproduce it in a --pure environment and I couldn't.
After a couple hours digging, I found that this snippet in my modified
.dir-locals file:
--8<---------------cut here---------------start------------->8---
(with-eval-after-load 'geiser-guile
(let ((root-dir (locate-dominating-file
default-directory ".dir-locals.el")))
(setq geiser-guile-load-path
(cons root-dir
(delete root-dir geiser-guile-load-path)))))
--8<---------------cut here---------------end--------------->8---
Was the culprit, especially the use of with-eval-after-load (which
turned out to be unnecessary).
This snippet allows to switch between git worktrees and always have the
geiser-guile-load-path (which configures both the Guile %load-path and
the %load-compiled-path) set correctly.
Here's the diff of my (fixed) .dir-locals in my Guix git checkout:
--8<---------------cut here---------------start------------->8---
~/src/guix$ git diff .dir-locals.el
diff --git a/.dir-locals.el b/.dir-locals.el

I am closing this issue, sorry for the noise!
