Thanks Max. I had tried something similar but still had 
<bsd.port.pre.mk> so it bombed.

Not really but I think it was due to my misunderstanding of what
kdeprefix did.  By not adding that to USE_KDE4 I still have access to 
KDE4_PREFIX without everything getting installed there.

The only thing I'm still trying to figure out is how to get the
difference, if any, between LOCALBASE and KDE4_PREFIX for the PLIST_SUB
on the KDE4 related options. If I put the following in pkg-plist

	%%DOLPHIN%%share/kde4/services/ServiceMenus/dolphin/pacpl.desktop
	%%KONQUEROR%%share/kde4/services/ServiceMenus/konqueror/pacpl.desktop
 
when it comes time to deinstall it fails because the paths are obviously
relative to LOCALBASE.  However, I don't want to hardcode the difference
in the paths, e.g. kde4, unless necessary, since it could change. It
seems like the thing to do would be to remove LOCALBASE from KDE4_PREFIX
and add that to PLIST_SUB, though I'm not quite sure how to do that. Am
I thinking about this in the wrong way?
