Hello,

./autogen.sh 
autoreconf: Entering directory `.'
autoreconf: configure.in: not using Gettext
autoreconf: running: aclocal -I config --force -I config
autoreconf: configure.in: tracing
autoreconf: configure.in: not using Libtool
autoreconf: running: /opt/local/bin/autoconf --include=config --force
configure.in:28: error: possibly undefined macro: AC_PROG_LIBTOOL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
autoreconf: /opt/local/bin/autoconf failed with exit status: 1
autogen.sh: error: autoreconf exited with status 0

any hints?
Thanks.
