Comment (by kencu):

 On SnowLeopard, you can quite easily use the latest linker that the `ld64`
 port supports, and you should. But it's a manual step, I'm afraid, and I
 don't know how it could be automated.

 It looks like the relevant step has been stripped out of the current
 LibcxxOnOlderSystems instructions
 <https://trac.macports.org/wiki/LibcxxOnOlderSystems?action=diff&version=70>,
 but you have to do this:

 8. **Snow Leopard Only:** Disable the variants corresponding to the older
 versions of ld64 in `/opt/local/etc/macports/variants.conf`.  This ensures
 that ld64 will be reinstalled using the appropriate variants in the
 future:
 {{{
 -ld64_97
 -ld64_127
 -ld64_236
 }}}
 9. **Snow Leopard Only:** Reinstall ld64 with the legacy variants disabled
 to use ld64-latest as the default linker and deactivate the bootstrap
 linker:
 {{{
 sudo port -v upgrade --enforce-variants ld64 -ld64_97 -ld64_127 -ld64_236
 sudo port -v deactivate ld64-127
 }}}
