New description:

 I've been experimenting with building various macports C++ libraries with
 XCode 4.5 DP2, with the compiler hardcoded to clang, and with '-std=c++11
 -stdlib=libc++' edited into configure.cxxflags in portconfigure.tcl:

 {{{
 default configure.cxxflags  {"${configure.optflags} -std=c++11
 -stdlib=libc++"}
 }}}

 I'll be the first to admit this is a somewhat exotic setup, but I've
 actually had surprisingly good success so far.

 One problem I have discovered is that my modified configure.cxxflags were
 not being passed along into the boost build system when building boost. In
 the Boost Portfile there is a line like this:

 {{{
 write_jam "using darwin : : ${filter}${configure.cxx} ;"
 }}}

 Which configures the user-config.jam file used by boosts build system.
 Based on the information here:

 http://www.boost.org/boost-
 build2/doc/html/bbv2/overview/configuration.html

 I think that this line should be modified to something more like:

 {{{
 write_jam "using darwin : : ${filter}${configure.cxx} :
 <compileflags>\"${configure.cppflags}\" <cflags>\"${configure.cflags}\"
 <cxxflags>\"${configure.cxxflags}\" <linkflags>\"${configure.cxxflags}
 ${configure.ldflags}\" ;"
 }}}
