Somehow I managed to miss the fact that Mac OS Forge released MacPorts v1.5. If you aren't familiar with MacPorts, it's the reincarnation of DarwinPorts under the Mac OS Forge / Apple banner. For any UNIX admin, or serious OS X-er, MacPorts is an extensive collection of UNIX tools ported to Mac OS X. I highly recommend it.
The new release appears to be largely focused on cleaning out the DarwinPorts cruft while adding a few bug fixes and feature enhancements. Upgrading your current installation is simple.
$ sudo port -d selfupdate DEBUG: Rebuilding the MacPorts base system if needed. DEBUG: Synchronizing ports tree(s) Synchronizing from rsync://rsync.macports.org/release/ports/ <snip> selfupdate done! $ port version Version: 1.520
After this, issue
port list outdated to see what needs to be upgraded. In my case it was
sqlite3. As always, your mileage may vary.
