slapd giving me startup errors.

[Peter Stickney <pstickney@pvpsc.com>]

I'm trying to start up an ldap server with openldap 2.3.4.  Ive got 
slackware 10.1.0, kernel 2.6.12.3.  I found this article [ 
http://docs.linux.com/article.pl?sid=04/03/01/1318258&tid=29&tid=14&tid=94 
] and have been following it.  Only when I go to start up slapd at the 
end of the article I get an error.

I use the command  ./slapd -f 
/usr/local/openldap/etc/openldap/slapd.conf -u ldap -d9

There's a lot of output, but at the end I get

slapd startup: initiated.
backend_startup_one: starting "cn=config"
backend_startup_one: starting "dc=pvpsc,dc=com"
bdb_db_open: alock package is unstable
backend_startup_one: bi_db_open failed! (-1)
slapd shutdown: initiated
====> bdb_cache_release_all
bdb_db_close: alock_close failed
slapd destroy: freeing system resources.
slapd stopped.

I have tried looking for the "alock package is unstable" line over the 
internet, but havent found much of anything.  Any help would be greatly 
appreciated.  thanks
