Lately it has been happening to me somewhere on nearly every build
run.

Checking the package databases on a couple machines shows multiple
examples, e.g.:

   % pkg_info -R vim-share
   Information for vim-share-8.1.0551:

   Required by:
   vim-8.1.0390
   vim-8.1.0551

and

   % pkg_info -R boost-libs
   Information for boost-libs-1.68.0:

   Required by:
   libcdr-0.1.4nb6
   libcdr-0.1.4nb6
   gource-0.40nb13
   gource-0.40nb13
   source-highlight-3.1.8nb7
   source-highlight-3.1.8nb7
   libvisio-0.1.6nb7
   libvisio-0.1.6nb7
   librevenge-0.0.4nb7
   librevenge-0.0.4nb7

It does not happen on every build, but it happens a lot, and when it
happens it's always a matter of leaving behind the entry for the prior
copy of the depending package, whether or not it's the same version.


handy check script:

   (cd /var/db/pkg && grep . */+REQUIRED_BY | sed 's,^\([^/]*\)-[^-/]*/+[^:]*:\(.*\)-[^-]*$,\1 \2,' | sort | uniq -dc)
