I see.  It's a build dependency of gobject-introspection, but not a run
dependency so it shouldn't get installed when you install the cups package.
If you don't need Zeroconf support you can disable the AVAHI option in
print/cups.  If you do want it you can disable the OPENGL option in
graphics/cairo.  That should take out the most expensive dependencies like
llvm.
