That would work great if I didn't want my cake and eat it too :) As Ryan pointed out in his reply, most users want current versions of ports, and I do too, with the exception of these PHP development-related ports. Do you know if it's possible to toggle back and forth? If I were to take a snapshot of the tree from some point in time to install some older things, would I be able to switch back to the main repo to install something else? I understand that there might be some cross-over problems if I'm installing something newer that might upgrade something older, but that's not something I'm terribly concerned about right now.

Thanks, Jeremy. I appreciate the quick response.
