>Description:
	If the port is already installed I get this:

Gantry comes with a set of default templates that
need to be written to disk. A typical location for these
templates is your web server document root.

Path for Gantry templates [/usr/local/www/gantry ]
/usr/local/www/gantry 
Created MYMETA.yml and MYMETA.json
Creating new 'Build' script for 'Gantry' version '3.64'
===>  Building for p5-Gantry-3.64
Building Gantry
rmdir: /usr/local/www/gantry: Directory not empty
*** Error code 1

>How-To-Repeat:
	See above
>Fix:
	First choice would be to fix the port so that it doesn't
	ask this question, and does the right thing on re-install.

	Second choice would be to mark it IS_INTERACTIVE and add
	CONFLICTS_BUILD on itself.
