Comment:

 Update for interested parties:

 - I'm going to tackle this ASAP, via our new port `glib2-upstream`.
 - Once that's done, I'll review and coordinate with Ryan relative to
 folding this functionality into `glib2-devel`. (And eventually `glib2`.)

 In terms of overall strategy:

 - Given the number of dependent ports, the overarching goal is to make the
 transition as seamless as possible.
 - To that end, two new segregated subports will added:
 `glib2-upstream-x11` and `glib2-upstream-quartz`.
 - The base port will remain as-is for backward compatibility, installing
 everything where it goes today. That way dependents can gradually be
 migrated to the new scheme.
