I think they should already be compatible with python3 since 1.2.9 (or 
1.3.1) if I'm looking at upstream git repository:

http://git.linux-nfs.org/?p=steved/nfs-utils.git;a=commitdiff;h=9f9289efda1a7eff26cd046997efc56c2de40534

So it's just a matter of changing the shebang and the dependency.

Question, why is this a recommends? The executable is using python(3) 
without any fallback mechanism I can understand that this is a "not 
often use binary", but shouldn't that be changed to a Depends?
