Thank you for the report. It's been fixed:

https://git.savannah.gnu.org/cgit/guix.git/commit/?id=eef6aa3c91df13f27999bfa911d5c40bf691a420

Guix users will get the corrected package metadata whenever they next
update their systems, and the website should reflect it shortly.

We were actually discussing these issues regarding build tooling

that affected you.
