[Geany] Can't launch newly created geany package on my Mac

[Norman Chonacky]

I've just installed the Geany 0.15 package under Mac OS X 10.4.11  
using an application called the MacPort transporter to compile and  
install a binary package for geany on my G-5. When I try to launch it  
from the Terminal command line I get the error "Geany: cannot open  
display" and the launch process terminates. Was I supposed to  
configure something before trying to launch it?
