It links fine for me, and I haven't heard any other reports of this, but can you please try adding a line: LIBADD+= z to usr.bin/clang/llvm-extract/Makefile locally, and see if that fixes it for you? At some point I've tried minimizing the number of libraries pulled in, and on my systems llvm-extract didn't use any of the compression functions. If you compile it differently, it could end up pulling in those functions anyway. Do you have any non-default settings in make.conf or src.conf? -Dimitry P.S. The clang600-import branch should be mostly ready for general consumption, except for a number of ports that are still problematic, see https://bugs.freebsd.org/224669
