So then one of thee things happened:

- There is some bug in port where pymol was rebuilt before libpng
- pymol didn't have a dependency on libpng listed (which would be a bug in the pymol port)
- pymol wasn't rev-bumped (or was rev-bumped after your selfupdate happened, and you unfortunately got the libpng bump but not the pymol bump)

Since this is macports-dev, you can probably investigate further and determine what actually happened on your machine.
