Re: boost1.57 test packaging

Hanspeter,
      I see that you are limiting the build of boost 1.58 to just
10.9/10.10. The MacPorts boost 5.18 packaging uses the patch at...

https://trac.macports.org/browser/trunk/dports/devel/boost/files/patch-apple-clang-no-libcxx.diff

with the comment...

                # error that occurs on OS X 10.7 and 10.8 due to the assumption
                # that if clang is the compiler in use it must be using libc++.
                # Apple Clang uses libstdc++ by default on these OS versions.
                # The patch adds an additional BOOST_* configuration flag
                # that is set if Apple clang is being used but libc++
                # is not.  This flag is then used to prevent boost or a
                # dependent package from using functions such as
std::forward that
                # are only available in libc++.  Fixes build of libcdr on these
                # OS versions without affecting build on 10.6 and less
(where clang is not
                # the default compiler) or 10.9 and up (where libc++
is the default).

It may be worth supporting 10.7/10.8 with this patch provided that the
test case from https://svn.boost.org/trac/boost/ticket/10785 compiles
okay under the clang++/libstdc++ combination. The bug report is silent
about which c++ library was used for the tested but I assume it was
likely libc++. Hopefully the bug is libc++-specific, otherwise there
isn't much reason to add boost 1.58 for 10.7/10.8 since we don't have
the option of the -std=c++11 workaround with libstdc++.
