Hi, This should have just been fixed in a40ac6271578ea061a8a07b2adbd6032a690ca70 (and/or with bd4f314bbacaaa56751be3a4769f2082be747d24). See also https://issues.guix.gnu.org/53238 for the original issue.
It builds and passes tests for me after these commits, can you do a guix pull and try again? John
