That's not a good sign. I still have in the store the tar file with
the hash indicated in the package and it builds fine. However, if I
'guix download ...' the file again I get a hash which is different
from the one in the package and also from the one in the hydra log.
I can imagine that melpa is building the tar file on the fly. Is guix
taking the time stamp as an input to determine the hash?
