Installation Problem

[beno <zope@2012.vi>]

Hi;
I'm trying to build the latest distro of openldap on a FreeBSD 6.1 box. 
Even with the standard config with no flags I get the error that the 
distro can't find the Berekely DB:

checking for db.h... yes
checking for Berkeley DB major version... 1
checking for Berkeley DB minor version... 0
checking for Berkeley DB link (-ldb1)... no
checking for Berkeley DB link (-ldb-1)... no
checking for Berkeley DB link (default)... yes
checking for Berkeley DB version match... yes
checking for Berkeley DB thread support... no
checking Berkeley DB version for BDB/HDB backends... no
configure: error: BDB/HDB: BerkeleyDB version incompatible

I had just reinstalled all my ports to BSD. But I went over to sleepycat 
and d/l'd the latest and ran the ../dist/configure && make && make 
install from the build_unix dir without a hitch (not the Java version, 
just the plain vanilla). But I still get the same error from openldap. 
What am I missing?
TIA,
beno
