This set of ports enables the use of the Gnome GUI from Guile scripts. The real work is in the guile-gnome-platform one, the other two are just dependencies.
Tested for build + successful run of nontrivial example programs on:
FreeBSD 11-stable, amd64 FreeBSD 12-stable, amd64, armv7, i386
(I have no other platforms available)
portlint - passes.
poudriere testport - passes
