Package: pbuilder
Version: 0.215
Severity: wishlist
Tags: patch

I have written an apt based dependency resolver for pbuilder.

It's based on the aptitude one with two differences
(aside from not using aptitude obviously):
- It ignores alternative build-dependencies similar to sbuild.
- It uses a local repository for the dependency package instead
  of installing it with dpkg -i --foce-...
  I didn't bother with generating a key and signing the repository.
  Instead I marked it as trusted in the source.list entry. This has
  the limitation that it requires apt >= 0.8.16~exp3.

Regards,
Felix
