None here.

For an "NG" tool in its infancy (i.e., little-or-no user base),
requiring the nearly-2-year-old make-3.82 should not be a problem.
However, I admit to being surprised that even debian *unstable* is
still using 3.81.  You have to go to experimental to get 3.82.
So, yes, that means it is a problem.
