Re: Build dependencies not being installed when building postfix for stretch

["Rebecca N. Palmer" <rebecca_palmer@zoho.com>]

git-pbuilder builds in a chroot, containing build-essential and the 
build dependencies.   (One reason for doing this is to have _only_ those 
packages available, and not anything else you happen to have installed, 
as a check that the declared build dependencies do include everything 
needed.)

However, before entering the chroot, it tries to run debian/rules clean 
*outside* the chroot; in some cases the clean step needs some of the 
build dependencies, so this can fail.

I'm not sure if this should be considered a bug, but this is what I use 
to turn it off:
