I committed the amaroK 1.3.3 update to the FreeBSD portstree a couple of days ago, go get it !
The amaroK dev team really worked a lot on the stability, and it should be (according to them) the most stable release..ever..
I've already managed to find a couple of bugs.. The amarok port installs two main binaries (amarok and amarokapp), the first one being a wrapper for the latter. If you've compiled the port with libvisual support, you'll have to run amarokapp in order to visualize any plugin, the wrapper will not work.
Another thing is user-defined "smart playlists", they do not work with PostgreSQL support enabled.
I've created bug reports for both issues.
