Bug#606699: pbuilder-satisfydepends-aptitude can't resolve packages from experimental

[Emilio Pozuelo Monfort]

Package: pbuilder
Version: 0.199
Severity: important
Tags: patch

Hi,

Since pbuilder-satisfydepends-experimental doesn't work well (see
bug #508403), I've tried -aptitude without much success. It doesn't
want to install packages from experimental, and just fails. Since
the sbuild aptitude resolver works for the same packages that fail
with pbuilder, I looked at it and came up with the attached patch
that solves all my problems with the aptitude resolver when using
experimental.

If you want to test it, some packages that fail are gtk+3.0/experimental
and clutter-1.0/experimental. If you need more examples to test,
let me know.

Best regards,
Emilio
