I see there were dumb editing errors in the last part of my updated =
compiled.mk : I messed up the quoting for my addition. So a new diff is =
needed to supply missing \'s for nested quotes and a missing quote ("). =
But I was more trying to suggest background information that would =
contribute to an official fix --instead of providing "the patches" =
directly: there may be better alternatives to my specifics.

It appears that I did not have the usual compiler/linker problems for
built devel/libcxxrt , devel/libc++ , and devel/boost-all on powerpc
using 10.0-STABLE's clang 3.4.1 --up to the boost-locale.* issues.
The point of this was to see if compiling and linking could work. The =
minor changes to
devel/libc++/Makefile and devel/boost-all/compiled.mk , while very =
small, were only
intended to enable the test in my local environment: I do not claim wide =
enough knowledge
of freebsd for general updates.

Context & sequence leading to the "success":

This does not have libcxxrt or libc++ prebuilt but does have clang 3.4.1
providing a "freestanding implementation" of C++11. This was to a =
PowerMac3,6
(G4 FW800), 2 GB RAM.
/usr/ports/... without the recent changes to =
/usr/ports/Mk/Uses/compiler.mk .
This last is so that clang will be used like it used to be used.
Then I got the following in place so the interesting stuff could be done =
together
without these mixed in:
configure for pkg, /usr/sbin/pkg, pkg portmaster, portsnap fetch =
extract,
portmaster pkg (an update), pkg icu gettext gmake binutils bisdon m4
perl5 gmp mpfr cmake cmake-modules mpc boost-docs boost-jam,
portmaster devel/icu (an update) print/texinfo-lite devel/perl5.16 (an
update)
(I've not looked into why icu is not found and used despite being =
present and
even built if missing. May be icu needs to be built with clang? I've no =
clue.)
Then I updated devel/libc++/Makefile and devel/boost-all/compiled.mk and =
did
portmaster devel/libcxxrt devel/libc++ devel/boost-all
(I did not select to have Boost.Python built.)
About the Makefile and compiled.mk adjustments:
On another powermac I had tried the sequence (before the
/usr/ports/Mk/Uses/compiler.mk changes):
portmaster devel/libcxxrt
portmaster devel/libc++
cmake refused during the last because it tried to pre-test the c++11 =
environment for
being a valid hosted c++ implementation (i.e., standard library present =
and working to
some extent), including testing use of -lc++ notation for linking. Such =
testing failed, of
course: clang is not yet a hosted implementation at this stage.
devel/libcxxrt did not complain but it has CXXFLAGS that includes =
-nostdlib and that
avoids the test of the hosted implementation status: free standing =
implementation
only.
So I manually added -nostdlib into CXXFLAGS for devel/libc++/Makefile =
and then
devel/libc++ built when I tried portmaster again.
devel/boost-all did not automatically look in /usr/local/include/c++/v1/ =
and
/usr/local/lib/ where devel/libc++'s build put things.
So for devel/boost-all I then added -I${LOCALBASE}/include/c++/v1 to =
cxxflags in BJAM_ARGS and =20
added linkflags=3D-L${LOCALBASE}/lib to BJAM_ARGS and also added =
-L${LOCALBASE}/lib to <linkoptions>
(just in case).
