Here is an excerpt of the code from run script

AC_THREADS=threadsyes

export AC_bdb AC_hdb AC_ldap AC_ldbm AC_meta AC_monitor AC_relay AC_sql \
       AC_accesslog AC_dynlist AC_pcache AC_ppolicy AC_refint AC_retcode \
       AC_rwm AC_unique AC_syncprov AC_translucent AC_valsort \
       AC_WITH_SASL AC_WITH_TLS AC_WITH_MODULES_ENABLED AC_ACI_ENABLED \
       AC_THREADS

if test ! -x /usr/sbin/.3 ; then
       echo "Could not locate slapd(8)"
       exit 1
fi

BACKEND=

This test is what's giving me the problem I rebuilt the openldap using 
src rpm
