Hello,
There is currently an issue involving lf, the package build used by Guix
pulls from the commit tagged r27, however since commit #a94015d, a %d is
replaced with a %v, and the build will fail with the %d. The diff can be
seen here:
Changing to a newer commit should be able to fix this error.
Thanks,
Tyler Wolf
