Comment (by ryandesign):

 Remember to use TracLinks.

 Following [d9edc1e9a30ed6801698548877d3ad8481a4acac/macports-ports],
 gnutls now fails to parse on Snow Leopard:

 {{{
 Failed to parse file devel/gnutls/Portfile: expected boolean value but got
 "{${build_arch} eq "i386"} || {${build_arch} eq "x8"
 }}}

 There's no reason to restrict the blacklisting to Snow Leopard or earlier.
 The gcc 4.2 family and older clang versions do not suddenly become able to
 compile this code on newer macOS versions.
