Bug#508403: pbuilder-satisfydepends-experimental doesn't always try higher versions

[Junichi Uekawa]

That's a very old and initial version of
pbuilder-satisfydepends-experimental.  I'm not sure what changed since
then, and I'm not sure how it's supposed to work.

Can you try the newer version? There should be a pbuilder from bpo,
and if you are a DD, you should probably have a sid box to develop on
anyway...
