I am attempting to configure apr-util on AIX 5.1 & on AIX 4.3.3.

I have no need for LDAP, and have tried to use the "without" directive but "configure" exits with
a failure stating:
        configure: error: could not find an LDAP library

Here's my configure command:

    CC="xlc_r"; export CC
    "./configure" \
    "--prefix=/usr/local/dms/apr-util-1.0.0" \
    "--enable-threads" \
    "--without-ldap" \
    "--without-ldap-include" \
    "--without-ldap-lib" \
    "--with-dbm=sdbm" \
    "--without-berkeley-db" \
    "--with-expat=/usr/local/dms/expat" \
    "--with-apr=/usr/local/dms/apr" \

Is there another means of omitting LDAP support, or is it a requirement for apr-util ???
