 There are a few different issues with this port build, depending on the
 platform.

 The following is what we're seeing for the latest buildbot jobs:

 Big Sur x86_64:

 {{{
 distutils.errors.DistutilsPlatformError: $MACOSX_DEPLOYMENT_TARGET
 mismatch: now "11.0" but "11.2" during configure
 }}}

 10.6:

 {{{
 error: invalid argument '-std=c++11' not allowed with 'C'
 }}}

 For 10.8/10.9:

 {{{
 In file included from src/core/lib/iomgr/gethostname_sysconf.cc:26:
 In file included from /opt/local/include/LegacySupport/unistd.h:92:
 In file included from /usr/include/unistd.h:72:
 /opt/local/include/LegacySupport/sys/unistd.h:76:16: error: unknown type
 name 'size_t'
                          void *buf, size_t size, uint32_t flags);
                                     ^
 }}}

 This might be a case of blacklisting older clang versions, and perhaps
 blacklisting Xcode clang entirely (if necessary).
