installed tree on Mavericks 10.9.2

[Ken G. Brown]

I’ve just installed the tree utility using Pallet.app gui for MacPorts.

I had tried earlier with Port Authority but had a few crashes. 

What is the best gui for MacPorts?

Now that tree apparently is installed, how do I run it, where is the executable?

Is there something I am missing in setting up to be able to run the MacPorts installed programs?

Any tips appreciated.
Thx,
