If you don't have LMDB, then everything still works; it just uses flat text
files (*.nzf) to save newly-added zone configuration instead of using an
LMDB database (*.nzd).  LMDB gives you better performance than flat files,
particularly on delete operations, but in terms of functionality it
shouldn't make any difference.

There were several bugs in the LMDB/NZD code though, which are being fixed
in 9.11.2. I don't recommend using LMDB until then.

In any case this turns out to be a moot point as a) you don't have LMDB
installed and b) it turns out catalog zones don't directly use NZF files
anyway. I was a bit confused about this when we discussed it in the
support meeting yesterday: catalog zones use the same configuration
parsing context as NZF files so they can configure new zones at runtime,
but they don't actually save zone configuration in the NZF files. The
configuration lives in the catalog zones themselves.
