fun with autoconf on Tru64

Hi all,
    I am having fun with !@#$#$@#$ autoconf. In the past I always used 
the configure in the RC tarball without (much) problem. As I am trying 
to be a good little commiter, I am trying to build my potential changes 
out of cvs and am starting with buildconf.

I have installed:
    gawk-3.1.1
    m4-1.4o
    bison-1.875
    flex-2.5.27
    autoconf-2.13
    automake-1.5
    libtool-1.4.3

I get warnings/errors during buildconf, and then syntax errors in the 
./configure after.

Any suggestions ?
