I'm not sure about the "b", but the issue seems to be you can't build anything
with c++ it appears, even though our build lines are identical:

Please try building a very simple c++ "hello, world" program with
/usr/bin/clang++ -stdlib=libc++
and see if your c++ compiler is working at all ---
If not, there's your issue --- and you'd need to reinstall something. We can't
do much if your /usr/bin/clang++ is broken.
If it works -- well then I don't know just yet -- we'd have to see...
