pbuilder-uml 0.199ubuntu4 (i386 binary) in ubuntu natty

 pbuilder-uml uses a User-mode-linux system, and builds Debian packages
 inside the UML image. 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.
 .
 Requires user-mode-linux to function correctly
 .
 "pbuilder-user-mode-linux create" uses rootstrap to create UML image
 .
 "pbuilder-user-mode-linux update" updates the image to the current state of
 testing/unstable/whatever
 .
 "pbuilder-user-mode-linux build" takes a *.dsc file and builds a binary
 in the UML
