X11 problem?

[Bee]

Installed gnumeric from macport
sudo port install gnumeric

$ which gnumeric
/opt/local/bin/gnumeric

$ gnumeric
Cannot open display:
Run 'gnumeric --help' to see a full list of available command line  
options.

$ echo $PATH
/usr/local/bin:/usr/local/sbin:/opt/local/bin:/opt/local/sbin:/Users/ 
Bee/bin:/Users/Bee/sbin:/bin:/sbin:/usr/bin:/usr/sbin

I can open X11, add gnumeric -- opt/local/bin/gnumeric to the menu  
and it runs with a font problem that I posted earlier.

Reading the "X11 problem?" post I get the feeling X11 is not needed  
and I should be able to run gnumeric straight from the command line.

How to?
