rb-gd installs but doesn't work

[garry@…]

installing rb-gd then calling

require 'GD'

from within irb gives:

Symbol not found: _libiconv_close Referenced from: /opt/local/lib/libgd.2.dylib Expected in: flat namespace

this is related to a similar bug for p5-gd but the workaround is different. basically the config stage doesn't include a link to libiconv.

I have a working portfile and necessary patch to add here
