Since commit 83e8336, gEDA/gaf builds with Guile 2.0 or Guile 2.2.
I haven't tested it with Guile 2.2 yet, but the only code snippet known not to be portable isn't part of gEDA/gaf any more and several people have used gEDA/gaf 1.10.0 with Guile 2.2 without problems, so I assume there's nothing more to do. I'm still leaving this bug open until this has been verified.
