Hey Alex, It appears when MK_LLVM_BINUTILS is set, a strip binary/link doesn't get installed. So /usr/bin/strip doesn't exist. This causes a problem when building packages since even ports-mgmt/pkg relies on strip. I'm working on a candidate patch to fix this right now. But if you beat me to the punch, all the better. ;-) Thanks, -- Shawn Webb Cofounder / Security Engineer HardenedBSD https://git.hardenedbsd.org/hardenedbsd/pubkeys/-/raw/master/Shawn_Webb/03A4CBEBB82EA5A67D9F3853FF2E67A277F8E1FA.pub.asc [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEA6TL67gupaZ9nzhT/y5nonf44foFAmE8wJkACgkQ/y5nonf4 4fphpA/8CIm0S2DGg5Hau2eKSPGLsgpbhmkj9kwpB4zXPdMm6Go7YqQFSlTXHvaI nyzP2X+QZgt4z794fUiiFzX/y0P2elW02WQZG60fJKLZ0RetG32SLT/IUG6tM6at Ngwwed5UEOMRfocdT5oSW7lt8kyZk7XRgWqx3zresEg/mNKsCj7LecLbX3J0UQeV naoDAmrTCAJVBqPka3dIW6VycTbbUiEI8ysZbnu5BHe/N4/uLXGUIiT0xvPozJNS pljHZc8Y4Sahf52AGEUa7b0EVZprGH1DwI2d1oi7iW8YinZ4Kw5TvwYgw3Zvglt1 A3pt0vIOBEfskCtxrQlDdhPqnVSs2v2jGAWhpupH3V5+em8cPvvpDl7Js2cZ3Leg 7X4nvWPTewM9PgnX7ToCZeKrGr02+hMLe77KQri6ymnVy5duFxD6+bjB9yugOeRO ADGnKRFxTq9J5KOuOa2wguJQ/q4DtVj+5N50gb9v/UWWGF174TPpL+nQ5UGTJB/f kIKnYCu+b9uHXXUHtLzdpCVCPklOsG8yquPdrN94N5276FkxRS2a5hmPn8GEy5fS YR30eXMQoc1gq5s+Q7Kqw89+lLPPmskmZ62Kmx/ib7boXL/cr/dWFfQEkRNmxoJM gvynHP+U68pEkoHyiSaMJ49yuqY+IfTSvYUWazDrSsy+/xMA0cQ= =EqXr -----END PGP SIGNATURE-----
