 This is the (partially sorted by GNU Emacs) list of ports from `port -vd
 rev-upgrade` that need to be updated:

 But when I try to rebuild my version of GNU Emacs with GCC7 I get in
 `configure.log`:

 {{{
 dyld: Library not loaded: /opt/local/lib/libffi.7.dylib
   Referenced from: /opt/local/lib/libgobject-2.0.0.dylib
   Reason: image not found
 }}}

 I've also seen `ld-127` form `port ld64-127` crashing, see attached
 screenshot.


 `port` itself has no proper plan to rebuild these invalid packages, it
 starts with `guile` (possibly trying to upgrade to new version 2.2.7_1 and
 never manages to finish (with "never" I mean a time period of three hours
 CPU use in `top`).
