>> problems. The dbm library must have been compiled to use fcntl (or lockf).
gdbm, as shipped by the FSF, compiles for fcntl or flock, depending on which it finds. I'd taken over maintenance (though lacking bug reports haven't uploaded a new package) but for my own use, built a version that did no locking at all (it interferes with kerberos V5 database locking, for one thing.) If I could come up with a good interface (environment variable? mode bits on the database?) I'd submit the patches for real...
