Re: dlz-bdbhpt-dynamic - a dlopen bdbhpt DLZ driver -- works!

> If you pull down another copy does it correctly link for you now?

It certainly does, yes, and your driver works, too! :-)

A few notes:

1. I configured it incorrectly first, thinking arg3 was path to
   database name, whereupon BIND faults with below stack trace. My
   fault, obviously, but you might want to look into that.
2. I had to modify bdbhpt-populate.pl to change flags = DB_CREATE
   only. Running BDB 4.7. Don't know why that is, and don't really
   have time to investigate. (Sorry.)

Thanks for your help -- nice job!

-- stack trace when incorrectly configuring named with 3 i/o 4 args:

BIND faults, though as soon as it opens the driver: this is about as
much of a stack trace as I can get at the moment:
