Unfortunately, qt4-* ports slice this idea. Because they don't use
LIB_DEPENDS, but a version dependant RUN and BUILD depends. I've coded a
"patch-recursive" target in my Mk/bsd.local.mk that can't depend just on
LIB_DEPENDS for this very reason (I needed the target so I can debug
crashes in kde4 programs, and have gdb's `list' command working).
