Ah, hmm - so I think I partly figured out why. (At least, enough to move
forward with what I'm trying to do.) The Guile package in Guix isn't
configured to look in GUILE_EXTENSIONS_PATH for native extensions. I
managed to work around this by doing this in a manifest for my project:
#+begin_src scheme
(define-public guile-search
(package
(inherit guile-3.0)
(native-search-paths
(list (search-path-specification
(variable "GUILE_EXTENSIONS_PATH")
(files (list "lib/guile/3.0/extensions")))))))
#+end_src
That said... is there a reason the Guile package doesn't already look
here by default?
