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 ? # ./buildconf using default Zend directory buildconf: checking installation... buildconf: autoconf version 2.13 (ok) buildconf: automake version 1.5 (ok) buildconf: libtool version 1.4.3 (ok) rebuilding configure configure.in:564: AC_TRY_COMPILE was called before AC_AIX configure.in:564: AC_TRY_RUN was called before AC_AIX configure.in:564: AC_TRY_COMPILE was called before AC_AIX configure.in:564: AC_TRY_RUN was called before AC_AIX autoconf: Undefined macros: ***BUG in Autoconf--please report*** AC_ACVERSION ***BUG in Autoconf--please report*** AC_TRY_DLOPEN_SELF ***BUG in Autoconf--please report*** AC_TRY_DLOPEN_SELF ***BUG in Autoconf--please report*** AC_TRY_DLOPEN_SELF ***BUG in Autoconf--please report*** AC_TRY_DLOPEN_SELF ***BUG in Autoconf--please report*** AC_TRY_DLOPEN_SELF ***BUG in Autoconf--please report*** AC_TRY_DLOPEN_SELF ***BUG in Autoconf--please report*** AC_TRY_DLOPEN_SELF ***BUG in Autoconf--please report*** AC_TRY_DLOPEN_SELF rebuilding acconfig.h rebuilding main/php_config.h.in configure.in:564: AC_TRY_COMPILE was called before AC_AIX configure.in:564: AC_TRY_RUN was called before AC_AIX configure.in:564: AC_TRY_COMPILE was called before AC_AIX configure.in:564: AC_TRY_RUN was called before AC_AIX
