I think I know the answer: .cache contains the compiled file for the operating
system declaration (clementi.go), and with the recent changes to how these are
parsed, it is incompatible.

Hopefully, this does not occur with "guix pull", and then it might be
considered normal... Is .cache actually necessary, since we generally
recompile from make files? Or is it needed since the make files do not
encode the precise dependency graph of the modules, as they usually do
for C code? If it is not necessary, could it be disabled by the project?
