hmm, I just realized, this is strictly speaking not necessary.

"stat -c %Y" means that guilt only works if GNU coreutils is
installed, which means that "touch -d @secs-since-epoch" should also
work.

This will be a problem on legacy systems such as Solaris (unless their
path puts the GNU utilities head of their System V-style utilities),
but that's going to be true of guilt in general, it looks like.
