that's not what I see:
users-Mac-mini:~ user$ g++ test.cpp
users-Mac-mini:~ user$ otool -L a.out
a.out:
/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current
version 120.0.0) /usr/lib/libSystem.B.dylib (compatibility version
1.0.0, current version 1197.1.1) users-Mac-mini:~ user$ rm a.out
users-Mac-mini:~ user$ g++ -mmacosx-version-min=10.7 test.cpp
users-Mac-mini:~ user$ otool -L a.out
a.out:
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0,
current version 60.0.0) /usr/lib/libSystem.B.dylib (compatibility
version 1.0.0, current version 1197.1.1)
Just using consistent macosx_deployment_target setting
in /opt/local/etc/macports/macports.conf and
-DCMAKE_OSX_DEPLOYMENT_TARGET option passed to cmake when configuring
darktable is enough to avoid these problems.

That's basically what macports documentation says about upgrading OS -
you have to rebuild everything. Same goes for changing
macosx_deployment_target option.
