#f is an elisp compatibility hack in Guile.
Use (format #f "v~a" version) instead, or simpler
(string-append "v" version).

Looking at the patch only and (I didn't test it, didn't do

Why are the tests disabled? (Are there none, do they need
additional packages not in Guix, ...) Maybe add a line like
