Comment (by RobK88):

 The build error being generated from my build in my local repo relates to
 sysroot:

 `clang: warning: no such sysroot directory:`

 It looks like new Portfile tries to set sysroot with unexpected results:

 {{{
 build.env       CC=${configure.cc} \
                 "CFLAGS=${configure.cflags} [get_canonical_archflags cc]
 -isysroot${configure.sdkroot}"
 }}}
