(py39 happens to be what is in use in my context.) Even devel/llvm*@lite depends on py39-recommonmark --and that in turns leads to the sequence: py39-sphinx, py39-requests, py39-urllib3, py39-cryptography, py39-setuptools-rust, and rust. (The dependencies look to be basically runtime and test dependencies.) devel/llvm* always seems to be tied to recommonmark . [I'll note that recommonmark is in the process of being replaced upstream my myst-parser but that also leads down the same sphinx and later dependency sequence from what I can tell.] The system-clang builds avoid needing recommonmark (or the like). May be devel/llvm*'s could be updated to allow selecting such an avoidance? May be what actually uses recommonmark (or the like) could be separated into its own port that could optionally be built/installed? (Just vague ideas.) [Separately, just curious: Which resource limitations stop the building of rust in your context?] =3D=3D=3D Mark Millard marklmi at yahoo.com
