error compiling openldap on configure

["Marco Strullato" <marco.strullato@gmail.com>]

Hi all, I'd like to build openldap on aix 5.2 with this compile options:
./configure --prefix=/opt/openldap-2.3.26-bdb --enable-slapd
--enable-backends=no --enable-bdb=yes


compiling fails because it seems can not find the library of bdb. But
library is there:

[root@bernini /tmp/openldap-2.3.26]# ls -l /opt/bdb-4.3.29/include/
total 248
-r--r--r--   1 root     system        88907 Sep 19 10:54 db.h
-r--r--r--   1 root     system        33577 Sep 19 10:54 db_cxx.h
