You can yell at the LMDB project for making an incompatible on disk 
format with no automatic handling of upgrades when going from 0.9 to 
1.0. It was a fun surprise when services failed to read their own 
databases, with error messages making zero sense (bind comes to mind).

Snippet from the commit log message:
databases/lmdb0: Add port for LMDB 0.9.x legacy ABI

LMDB 1.0 introduced an incompatible on-disk format change and subtle
API breakage: applications that compiled cleanly against 1.0 headers
could fail silently at run time. Known affected ports include dns/knot3,
mail/bogofilter, and mail/postfix; the postfix issue has been confirmed
upstream. Linux distributions such as Arch Linux have observed the same
breakage. Samba can also be affected in certain configurations.

Because the regression is not detectable in an -exp build run -- the
postfix failure only manifests at run time, and bogofilter was caught
only because post-build self-tests happen to exercise this path -- we
cannot rely on package builds to validate the 1.0 upgrade.

This commit introduces databases/lmdb0 as a holding port for the 0.9.35
