multistrap dependency is broken (multistrap version in repositories too old)

$apt-cache showpkg pdebuild-cross | grep -i Dependencies -A 5
Dependencies:
2.2.17 - gettext-base (0 (null)) multistrap (2 2.1.9) fakeroot (0 (null)) pbuilder (0 (null)) xapt (5 2.2.17) svn-buildpackage (0 (null))
....

http://packages.ubuntu.com/oneiric/multistrap - version 2.1.6 (not 2.1.9)

http://packages.ubuntu.com/oneiric/pdebuild-crosshttp://packages.ubuntu.com/oneiric/pdebuild-cross - depends on multistrap 2.19

Evil workaround - download debian source code build binaries and install
