3rd Party Audio Units, Logic Pro not seeing 3rd party AUs Options

[chance]

I recently switched from Cubase to the latest version of Logic Pro. I reinstalled my plug-ins as Audio Units...Darbuka, Symphonic Choirs/Orchestra. The components are in the proper directory - Library>Audio>Plug-Ins>Component(I made sure to download the latest updates). Unfortunately, Logic Pro does not seem to see them. The only AU's it loads are the native Apple plug-ins. I tried using the AU manager in Logic to rescan but still have had no success. From what I have read, Darbuka, at the very least, should be compatable. I think I must be missing something. Anyone have any ideas?

Many thanks for your time.

Obvious "stupid thing" that may work: repair permissions with Apple disk Utility.

Less obvious: if you're on an Intel Mac, are the plug-ins UB?

If it's neither, it'll be hairy
