this is related to the addition of Rules-Requires-Root.  When run
without fakeroot it's not possible to run such `chmod` commands.  In
fact, they are most likely always wrong to run them anyway…

I'll see them when I can fully build the package ;)


In d/copyright, that boilerplate-y thing you copied into the Comment
field, IMHO you should just get rid of it.  Also, it's missing many of
the years in the copyright claims: a copyright claim without a year is
at most an legal headache and at worst invalid.
