I'd like to add a pkgsrc target "show-depends-dirs" which will print the
directory part of the top level {BUILD_,}DEPENDS for a given package.
This does _not_ recurse the dependency tree, but only shows the top level
packages.

The target is useful for extracting a complete depends tree for all of
pkgsrc without lots of repetition.  

example:

dan@zomby 142 # make show-depends-dirs
 audio/esound graphics/imlib graphics/fnlib graphics/freetype-lib www/libghttp lang/perl5


Comments?

Thanks
-Dan
