After I recompiled it and installed it on the test system (which had its zpools created, but never mounted) I was able to mount the osts on that system for the first time.  I can't quite declare victory just yet, as I still need to perform the process on a system with data.  But I'm fairly confident that the data will be safe.

The 0.6.4.1 is the latest stable release, which included fix of the
issues/2523.
