how to compile recent openldap on Centos 5.5

Hello,

I tried to compile the Release 2.4.23 of openldap on my centos 5.5 server.

It fails with:

checking db.h usability... yes checking db.h presence... yes checking for db.h... yes checking for Berkeley DB major version in db.h... 4 checking for Berkeley DB minor version in db.h... 3 checking if Berkeley DB version supported by BDB/HDB backends... no configure: error: BerkeleyDB version incompatible with BDB/HDB backends

I do have db4 installed:

db4-4.3.29-10.el5_5.2 db4-devel-4.3.29-10.el5_5.2 db4-utils-4.3.29-10.el5_5.2

What may I do wrong? Any sugesstions?

Thanks and regards . Götz
