bug#52650: Guix pull fails building package cache

[André A . Gomes]

Hi,

I got the following error after issuing guix pull.

--8<---------------cut here---------------start------------->8---
building package cache...
/builder for 
`/gnu/store/6z0pny4mqnhrakqxs1yca5lnxjd1xszr-guix-package-cache.drv' failed to 
produce output path 
`/gnu/store/9spwrk8l40kpi110q47ckay0znmjzbdb-guix-package-cache'
build of /gnu/store/6z0pny4mqnhrakqxs1yca5lnxjd1xszr-guix-package-cache.drv 
failed
--8<---------------cut here---------------end--------------->8---

And the log says:

--8<---------------cut here---------------start------------->8---
(repl-version 0 1 1)

'/gnu/store/c68ygnsa87mqzfnrnkp798qi3jdsixh0-profile'...
