Comment (by ryandesign):

 See the comment I added to the Portfile in
 [79bcaad0315c9229ee841064701ab8b9fbff47ed/macports-ports]:

 {{{
 # Don't set "supported_archs noarch" because although it is a header-
 # only library, it needs the right C++ stdlib flag.
 }}}

 When supported_archs is noarch, MacPorts base clears the value of
 configure.cxx_stdlib so we don't know what stdlib to build for. This
 causes problems on systems where the MacPorts stdlib default is different
 from the compiler's (i.e. on 10.6-10.8).
