smartmontools update database error

[Chris Murphy]

chris$ update-smart-drivedb 
/opt/local/share/smartmontools/drivedb.h.error: rejected by /opt/local/sbin/smartctl, probably no longer compatible

I get the same error prefacing with sudo. This is smartmontools 6.0, built with Macports 2.1.3, XCode 4.6, on 10.8.2. 

The expected result, which I get on Fedora 18 from package smartmontools-6.0-2.fc18 is:

root# update-smart-drivedb
/usr/share/smartmontools/drivedb.h updated from trunk

Also, this was working with smartmontools 5.42 built with Macports/XCode maybe 6 months ago.

Any suggestions?
