Nothing! :-)
The store item that substitute-binary created on the first run is
actually invalid. You can see that from the fact that you get an error
if you run, say:
guix gc --references /gnu/store/iw3jn6a1avv78pp5v2cv42vyh0d8zi0g-guile-toxcore-0.1-6a9fbe0
So you can either “rm -rf” it (use with care!), or, better, run ‘guix
gc’, which will automatically remove it and other invalid items.
(A store item is considered valid iff guix-daemon or guix-register has
added it to db.sqlite. guix-daemon does that upon successful
substitution or build.)
HTH,
