This seems wrong. At least last time i looked at the 'replace' target, it 
moved the +REQUIRED_BY file aside to be able to pkg_delete the pkg, but 
then move it back.

My guess for the real problem at hands is that for either direction of 
dependencies ("up" using +REQUIRED_BY or "down" using @depends lines and 
whatnot in +CONTENTS files), they only give data for one level, and care 
needs to be taken to walk the tree recursively.

AFAIK this was never implemented for the places of pkgsrc and pkg_* when 
that change was made in pkgsrc, and it _may_ be the problem at hands.
