 * sys-devel/clang:14 is missing! Cannot use LLVM slot 14 ...
 * Using LLVM slot 13 to build
 * Rust is using LLVM version 14 but ld.lld version belongs to LLVM version 13.
 * You will be unable to link www-client/firefox. To proceed you have the following options:
 *   - Manually switch rust version using 'eselect rust' to match used LLVM version
 *   - Switch to dev-lang/rust[system-llvm] which will guarantee matching version
 *   - Build www-client/firefox without USE=lto
 * ERROR: www-client/firefox-99.0::gentoo failed (setup phase):
 *   LLVM version used by Rust (14) does not match with ld.lld version (13)!
