We do something similar using prebuilt (pkg fetch) or locally built
(make package) packages by:

  1) untarring the .pkg:
     cd /tmp && tar xzvf {/usr/ports/packages/All,/var/cache/pkg}/...

  2) unpacking the manifests:
    cat -- +COMPACT_MANIFEST | jq -a 'del(.shlibs_required,.deps)' > \
    cat -- +MANIFEST | jq '.' > MANIFEST.tmp

  3) removing unecessary files and dependencies:
     vi *MANIFEST.tmp
       :s/DOCS": "on/DOCS": "off/
     rm -rf ./usr/local/{same files and deps as vi}

  4) and repacking into a new, minimal pkg:
     mv MANIFEST.tmp +MANIFEST && \
     tar cf - ... | (cd / && tar xfBp -) && \
     pkg create -M +MANIFEST

This tends to be easier than patching port/{Makefile,pkg-plist,files/...},
keeps /var/db/pkg/local.sqlite valid and works well with 'pkg audit'.
Should also, theoretically, be easy enough to roll into a metaport.

Thanks to Devin for the original idea.
