Not entirely sure what you're saying but here's how I setup my checkout from the svn.
Rename the folder "Ace3" to "ag_UnitFrames".
Move \ag_Unitframes, \ag_Extras, \ag_Options to your \AddOns-folder. You don't need the andreasg or the break19 folder.
In other words, don't put \ag_Options inside \ag_Unitframes.
Ah thanks dude. Didn't notice they were 3 completely seperate addons now. Works fine again. :)
