My current machine's state: FreeBSD 12.0-RELEASE-p11 r354060 CHTHONIXIA amd64 Recently, LLVM was updated to version 9. I do not recall why; but I think some port required version 9. Since 9 appeared to become the default version I deinstalled 8, assuming LLVM 9 was preferred. But now I'm not sure if LLVM 9 was set to the default version for Freebsd, or even if it is needed. Now I need to update firefox, which attempts to install LLVM 8. Can I dispense with LLVM 9 by a deinstall, and depend on LLVM 8 for a functioning, X-enabled, desktop? Or must I have both LLVM 8 and 9 as things stand now for 12.1? Thanks, Joe
