Hi Faheem,

r-cran-scales was built in Sid, where 3.0.1-3 was the latest version at that
time, and therefore r-cran-scales demands it.  The backport in Wheezy has a
lower version number, and therefore does not satisfy the demand.

One could consider adding systematically the magic tilde to the version numbers
passed to ${R:Depends}, but at that point, I think that it is even better to
implement a versionned R API number.

Have a nice day,
