It took me a while, but here they are, wrapped as a Christmas gift! :-)

You also have to take /usr/bin/dpkg-cross from a Debian system and probably
want to hardcode crossbase=/wherever/you/want, unless you're root.

BTW, I'd still really like to have some scripts so I can install (from binary
or from sources) Debian binaries in my home dir on a Red Hat or Solaris box.
Wishful thinking?
