Following Nat's suggestion, I have recorded the console log and sent that to him. But for anybody else interested, here are the final lines of the output (partially shortened for clarity), and it seems that gtk can't be found:

PHENIX-1.7.1-743 Running python script /Applications/PHENIX-1.7.1-743/Contents/phenix-1.7.1-743/phenix/wxGUI2/Coot.py

PHENIX-1.7.1-743 Traceback (most recent call last):

PHENIX-1.7.1-743 File "<string>", line 1, in <module>

PHENIX-1.7.1-743 File "/Applications/PHENIX-1.7.1-743/Contents/phenix-1.7.1-743/phenix/wxGUI2/Coot.py", line 24, in <module>

PHENIX-1.7.1-743 import gtk

PHENIX-1.7.1-743 ImportError: No module named gtk

Sorry for the multiple emails, but I just remembered that the
procedure below is more trouble than necessary - if you launched
Phenix from the icon, you can still get to the console by running
Apple's Console.app, which is in /Applications/Utilities, or this
command:

open -a Console

This should have all of the Coot output.
