The OpenLDAP build environment relies on non-standard versions of

configuration tools:

Autoconf 2.13.1

Automake 1.4a

Libtool 1.4.3

The autoconf/automake releases used are available at:

ftp://ftp.openldap.org/pub/tools/

The libtool release used is available from:

ftp://ftp.gnu.org/

but with ltmain.sh replaced with versions found in this directory.
