Comment 2 for bug 476036

Excerpt from a recent email (<20091121195151.GB32374@rivendell>) on debian-devel:

"In general it should work, but you're right that we have a problem
here with the buildds running an old version of sbuild (there are still
many buildd in that situation) because they do "dpkg-source -x" outside
of the buildd chroot where quilt is not installed even if you added
quilt in your build-depends.

AFAIK newer sbuild should do "dpkg-source -x" in the chroot where quilt is
installed due to build-depends and the .pc directory is then created
at unpack time."

So even if we do upgrade it outside the chroot, some stuff will still not work.
