Comment (by AgilentGCMS):

 I checked that I only have one version of `clang` installed via macports.
 However, trying to install the binary version failed:
 {{{
 $ port -b upgrade clang-9.0
 --->  Computing dependencies for llvm-9.0
 Error: Failed to archivefetch llvm-9.0: Binary-only mode requested with no
 usable archive sites configured
 Error: See
 /Users/sbasu1/packages/macports/var/macports/logs/_Users_sbasu1_packages_macports_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_llvm-9.0/llvm-9.0/main.log
 for details.
 Error: Follow https://guide.macports.org/#project.tickets to report a bug.
 }}}
 Trying to upgrade `libffi` again tried to build `gobject-introspection`,
 which fails :-(
