Didn't find a related ticket in trac yet, so I'm posting this here:
Workaround applied successfully on OS X 10.7.5 (Xcode 4.6.3) to libvisio
and libcdr in local port repo [1]:

if {${configure.cxx_stdlib} eq "libstdc++"} {
    configure.cppflags-append "-DBOOST_NO_CXX11_RVALUE_REFERENCES"
}

I do not know whether this is a "correct" solution - local tests however
confirmed so far that the results are as expected. Applied, successfully
compiled, installed and tested with libvisio (git master) as well as
libcdr (git master) on Lion: the command line tools of the libraries
produce expected results, and import in Inkscape using the shared
libaries also works (apart from a known regression in inkscape trunk
with CDR import not related to the recent boost upgrade).
