tramp install bug?

[kgold]

Trying to install tramp, I get this:

        tramp-2.1.3> ./configure --with-contrib
        configure: Tramp 2.1.3
        checking for gmake... gmake
        checking for reasonable gmake version... ok
        checking whether gmake sets $(MAKE)... yes
        checking for /usr/gnu/bin/emacs-20.7... yes
        checking for /usr/gnu/bin/emacs-20.7 flavor... emacs
        checking for /usr/gnu/bin/emacs-20.7 version... nok
        configure: error: Tramp 2.1.3 is not fit for GNU Emacs 20.7.1 
                (rs6000-ibm-aix4.3.3.0, X toolkit)

Question 1: My centrally administered system has emacs-20.7,
emacs-21.2, and emacs-21.3.  Could the install script be finding the
older one and stopping before it finds the newer one?  Can I just hack
out the test from 'configure'?  Is this a bug?

Question 2: I'm still using 20.7 because I could never get 21.3
working completely.  Is there a tramp version that works with 20.7?
