 okay, so you have stuff installed outside of MacPorts (and Homebrew) as
 none of these install stuff in `/usr/local/*` - that is something you will
 have to resolve before anyone (or at least me) will do anything about this
 ticket. You will need to show that this is an issue on a clean system.

 I guess it's possible that if the {{{.so}}} files from {{{glib-
 networking}} were compiled against a different, already-installed GLib/GIO
 ABI it could cause such a build failure. Can you try do (temporarily)
 deactivate the {{{glib-networking}}} port and see if that fixes the
 failure. That at least would give possibly an actionable thing to try and
 fix in the sense that it is a MacPorts issue then and not related to stuff
 you have installed outside of the package manager.
