www/yelp included twice in gnome2-lite

[Niclas Zeising]

I've been working a little on stripping down gnome further, removing the 
dependency on mono and so. While rummaging around in the makefiles for 
gnome2 and gnome2-lite I noticed that www/yelp is included in 
run-depends twice in gnome2-lite. First unconditionally in the Makefile, 
and then conditionally in the gnome2 makefile. Is this on purpose, or an 
oversight? If It's an oversight, the fix probably is to remove line 24 
from gnome2-lite/Makefile.
Regards, and Happy New Year!
