This sounds like a question for the comp.databases.berkeley-db

Yes this is the problem. Xen doesn't support this assembly-language
mutex nor does it support the nptl glibc (and bdb). So far it has been
discussed on the Xen mailing list but no solution has been found. I
guess running OpenLDAP on xen is not that common yet so no one has any
real good advice for building bdb.
RedHat has a bug report on this issue but it is marked "Won't fix" since
RHEL is not supported on any non-NPTL architecture, which is kind of
ironic since RHEL is throwing their weight behind xen which currently is
a non-NPTL architecture. I'll try an older version of db4 from RHEL3
compiled without nptl support and see if I have any luck. If not, I'll
degrade to an dbm backend. I'm sure Redhat will address this issue in
RHEL5 (which will ship with xen 3.0).
I'm assuming by a "dbm" backend, you mean ldbm. Of course, ldbm is not
recommended for use, because of its many problems. Honestly, if you are
looking to run a directory service, I would highly advise you dump Xen, and
use something where BDB is supported (and I'd suggest running OpenLDAP
2.3.20 (or higher, if newer releases have been made by the time you get to
it)).
