fcntl is the only scheme that will work across NFS, so you'll have to
tune config.h on all machines to #undef HAVE_LOCKF and #undef HAVE_FLOCK
before doing make (or issue make clean after modifying config.h). That
way, bogofilter will use fcntl.

Of course, the clients will need to have client-side locking support
(most BSDs don't) and the NFS server must support server-side locking
support (that's usually no problem).
