pbuilder 0.199ubuntu4 (i386 binary) in ubuntu natty

 pbuilder constructs a chroot system, and builds a package inside the
 chroot.
 It is an ideal system to use to check
 that a package has correct build-dependencies.
 It uses apt extensively, and a local mirror, or a fast connection
 to a Debian mirror is ideal, but not necessary.
 .
 "pbuilder create" uses debootstrap to create a chroot image.
 .
 "pbuilder update" updates the image to the current state of
 testing/unstable/whatever
 .
 "pbuilder build" takes a *.dsc file and builds a binary in the chroot
 image.
 .
 pdebuild is a wrapper for Debian Developers, to allow running
 pbuilder just like "debuild", as a normal user.
