 Instead of trying to parse debian/control and install each build-dep
 and satisfy each build conflict as currently in
 /usr/lib/pbuilder/pbuilder-satisfydepends and
 /usr/lib/pbuilder/pbuilder-satisfydepends-experimental, the idea is to
 generate a .deb in pbuilder-satisfydepends-aptitude with the build
 dependencies as dependencies and then install it.

 (See attached pbuilder-satisfydepends-aptitude.)
