I think 5b35c9adc899749a0bd96a0e6d2c3bbf88e38963 fixes the issue.

David, can you try the same thing in ‘guix repl’ instead of ‘guile’?  It
works for me.

(When you’re just running ‘guile’, you’re likely loading modules from
/run/current-system/profile/share/guile, which may come from an older
revision than the one ‘guix describe’ prints.)

Thanks,
Ludo’.
