Bug#786690: pbuilder fails to builds package with dpkg-dev 1.18.0 (dpkg-buildpackage -S)

[Yves-Alexis Perez]

Package: pbuilder
Version: 0.215+nmu3
Severity: important

Hi,

with the recent update to dpkg-dev 1.18.0 in unstable, pbuilder fails to
build packages for me. This is apparently because dpkg-buildpackage -S
fails now if build-dependencies are not satisfied.

One point of using pbuilder is to be able to not pollute the host system
with a lot of build-dependencies for various packages, since they'll
only be installed in a chroot.

I don't know if the behavior should actually be reverted in
dpkg-buildpackage or something changed in pbuilder, but if the
assumption doesn't stand anymore, it really needs to be advertised more.

Regards,
