Yes... I recently released an application that uses guile-gnome-platform, 
and had several reports of users bumping into exactly this when building 
the dependencies.

The current Fedora RPMs patch g-wrap-2.0-guile.pc.in, dropping the 
_INSTALLED suffix from those substitutions.  An OpenSuse user discovered 
the same fix, and a similar patch was posted to guile-gtk-general last 
April.


So while perhaps your suggestion (2) above ought to be considered,
if you were to patch like this, pkgsrc would at least be in good 
company...
