How do I inform the ports > that they may *only* use the version(s) in base? In general you can't. There are many reasons including: the base llvm doesn't include the requisite cmake bits for cmake based ports, some ports use unstable APIs and require specific LLVM versions, and some use LLVM tools or libraries that aren't built/installed as part of the base system. There are probably some ports where the base clang is fine but that's probably mostly down to someone getting USES variables right. -- Brooks --45Z9DzgjV8m4Oswq Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJY5WbqAAoJEKzQXbSebgfAl6wIAIjDjxR6G4gWb3zOVsomhiku uxvfzSeZ3wmj57ZQMUUsKvqFjd5TwT4nUan9aJLdvx+8PYM/0BIupLGKtBAi4Cm/ o4qay2u7kO+qWuLZ2zar1SQ7Gq4vOkb2KP/aOJFimLjfOeRVnvwrBXvqaVkAwgE4 Ket7gfDJlHCR72t66gaMbHfGkqFPJ2FUnPWNJjUMm3Rh+Mqu/dVwJQOslXiT93cP eQA/ehaJ+xSxVDxbEufCBRyLv//r/yHLbUFnN5p0UgVzFayc29RaFu5bQHlUiiwL rXHQadmd9duTrnS9cLibkj8v7xs9HD2v1qOX4Gs2QwOuOUY572gAiqoowG4yoHQ= =52u4 -----END PGP SIGNATURE----- --45Z9DzgjV8m4Oswq--
