This is practically an FAQ -- I sure didn't know how to do it until 
someone posted it.

First -- install pkgdepgraph and pkglint.  Then run the following:

	lintpkgsrc -i >ood-list
	pkgdepgraph -D ood-list >del-list
	pkgdepgraph -R ood-list >rebuild.sh
	pkg_delete `cat del-list`
	sh rebuild.sh

That generally works, though you sometimes need to edit ood-list to 
delete packages that are no longer known.  And of course, you always 
take the risk that something will no longer build.
