How to bootstrap pkgsrc on a system without ftp or file

[David Brownlee <abs%absd.org@localhost>]

        Bootstrapping pkgsrc on a system which needs both ftp and file
        seems to choke at the moment - it tries to build nbftp and
        finds it needs file... but then chokes on downloading the
        distfiles for libtool or file.

        when bootstrapping on a system which doesn't have a 'good'
        ftp, if a distfile is needed maybe it should just error
        out with a message saying to download the distfile (and/or
        try skipping the need for file and libtool)...

        What do people think?
