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)' > \
COMPACT_MANIFEST.tmp
cat -- +MANIFEST | jq '.' > MANIFEST.tmp
3) removing unecessary files and dependencies:
vi *MANIFEST.tmp
:s/DOCS": "on/DOCS": "off/
:g,share/doc,d
...
rm -rf ./usr/local/{same files and deps as vi}
4) and repacking into a new, minimal pkg:
mv COMPACT_MANIFEST.tmp +COMPACT_MANIFEST && \
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.
YMMV,
Roger
