Pbuilder problem

[Paul van der Vlis <paul@vandervlis.nl>]

Hello,

I use pbuilder for backporting packages. My problem is that a package
does not build, when there are build-dependencies from backports.
What can I do to make this work?

Some more info:

For example the package dh-linktree does not build, because debhelper >=
11 is needed, what's in backports. How do you backport such a package
with pbuilder?

I will add my .pbuilderrc as an attachment.

The error is:
dpkg-checkbuilddeps: Unmet build dependencies: debhelper (>= 11)
dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied;
aborting
dpkg-buildpackage: warning: (Use -d flag to override.)

With regards,
Paul van der Vlis
