 On 10.7, and I think likely all systems not configured to use libc++, we
 see:

 This looks to be occurring because we are trying to link in libgcc in ABI5
 mode rather than ABI4 mode. In c++ files a flag is added automatically by
 the cxx11 PG to fix this, but this flag is not automatically added to the
 objective c++ flags (maybe should be?), so it errors out with an ABI
 mismatch.

 The solution is to add that ABI-forcing flag to the ObjectiveC++ build
 flags:

 {{{
 if {[string match *clang* ${configure.cxx}]} {
     build.env-append        OBJCXXFLAGS="${configure.objcxxflags}
 [get_canonical_archflags objcxx] -D_GLIBCXX_USE_CXX11_ABI=0
 -stdlib=${configure.cxx_stdlib}"
 } else {
     build.env-append        OBJCXXFLAGS="${configure.objcxxflags}
 [get_canonical_archflags objcxx]"
 }
 }}}

 and then the build succeeds:
 {{{
 $ port -v installed texlive-bin
 The following ports are currently installed:
   texlive-bin @2018.47642_8+x11 (active) platform='darwin 11'
 archs='x86_64' date='2018-12-13T14:16:40-0800'
 }}}

 I don't think if we should just add ` -D_GLIBCXX_USE_CXX11_ABI=0` to all
 builds. It's only useful when using libgcc. For our purposes, adding the
 flag is the `configure.cxx_stdlib` is not `libc++` would probably be the
 right test...
