I get the same thing.

Hum, weird because I get this:

/gnu/store/rr2cnfygjh2bkv7cysva5i8h0nil6gla-guix-package-cache.drv

and you get:
/gnu/store/k4ih7z9q04nghfvw4by007z8ijskghkn-guix-package-cache.drv.

Do you have a custom channel file?  Usually, this kind of error come
from a conflict between the packages from upstream (commit 652a03888)
and local packages.

All the best,
simon
