OK, I am going to retract this suggestion.  The real reason, I think, 
that make package-depends is so slow is that invoking make is so slow. 
Try adding these lines to /usr/ports/Mk/bsd.port.mk:

	@for dir in ${_LIB_RUN_DEPENDS:C,[^:]*:([^:]*):?.*,\1,}; do \
		(cd $$dir; ${MAKE} xxx); \


Then cd to /usr/ports/x11/gnome2 and type

make yyy

All it is supposed to do is list the names of the immediate 
dependencies.  Even this is dead dog slow!!!  And the problem is, there 
simply is no other way to find out the name of the package except by 
invoking make in the directory.  So even if all the +DEPENDENCIES are in 
/var/db/pkg-name, even to find pkg-name is going to take a long, long time.

Basically I think we are stuck on making "make package-depends" go any 

However I do think that the modifications I made to pkg_create go a very 
significant way to solving the problem of registration taking so very long.
