First, as a user of the Boost libraries, I'd like to say thank you to
Noel and all the testers for providing the testing resources.

OK, so you cannot install libc++ to the standard location.
Let's try the following and see how it goes:

1. Download and build libc++.

2. Move to "SOME_PATH/libcxx/lib" ("SOME_PATH" is the location
where you downloaded libc++). Make a symbolic link or a copy of
"libc++.1.dylib" as "libc++.dylib" in the same directory.

3. Copy "cxxabi.h" to "SOME_PATH/libcxx/include"
and "libc++abi.dylib" to "SOME_PATH/libcxx/lib".

4. Run the test runner script with
* adding "-ISOME_PATH/libcxx/include" to <cxxflags>,
* adding "-LSOME_PATH/libcxx/lib" to <linkflags>,
* adding "SOME_PATH/libcxx/lib" to environment variable "DYLD_LIBRARY_PATH".
Maybe something like
    env DYLD_LIBRARY_PATH=SOME_PATH/libcxx/lib python ...
