Comment (by reneeotten):

 isn't the problem here {{{error: thread-local storage is unsupported for
 the current target}}}? I see that the Portfile uses
 {{{compiler.thread_local_storage yes}}} but we also know that this
 currently is not sufficient to select a proper compiler. I think Marcus
 has made the changes in base already to make sure that this will work
 correctly in the future, but for now manual blacklisting of compiler is
 still required. Admittedly I couldn't figure out which compiler is present
 in Xcode 6.2, but if it's below version 8 it will not work. I am sorry if
 I'm saying obvious things here and you already considered this...


 See the discussion listed below:
 # build fails with "error: thread-local storage is not supported for the
 current target"
 # setting "compiler.thread_local_storage yes" does not work, so for now
 just use blacklisting
 # See: https://lists.macports.org/pipermail/macports-
 dev/2019-November/041503.html
 compiler.blacklist-append {clang < 800}
