Comment (by dstrubbe@…):

 I'm don't think this is a good idea for gd2, because it recommends linking
 libvpx according to its config binary:
 {{{
 gdlib-config --libs
 -lgd -ljpeg -lz -L/opt/local/lib -lpng16 -L/opt/local/lib -lfreetype
 -L/opt/local/lib -lfontconfig -lfontconfig -L/opt/local/lib -lXpm
 -L/opt/local/lib -lvpx -L/opt/local/lib -ltiff -liconv
 }}}
 Everything else in this list is depends_lib for gd2. As a result, a code
 which naturally uses the output of this command in a configure script to
 decide how to link will fail if libvpx is no longer installed.

 On the other hand, the depends_lib port:expat does not seem to be
 dynamically linked into any library or executable from gd2, so I wonder if
 it really needs to be depends_lib.
