How to use binary distribution of Cling (mac)?

[canadaduane]

I’ve downloaded the latest binary of Cling and can run it from the Terminal. However, it reports that it cannot find various standard libraries:

ERROR in cling::CIFactory::createCI(): cannot extract standard library include paths!
Invoking:
  LC_ALL=C /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++   -O3 -DNDEBUG -xc++ -E -v /dev/null 2>&1 >/dev/null | awk '/^#include </,/^End of search/{if (!/^#include </ && !/^End of search/){ print }}' | GREP_OPTIONS= grep -E "(c|g)\+\+"
Results was:
With exit code 256
input_line_1:1:10: fatal error: 'new' file not found
#include <new>
         ^~~~~
Warning in cling::IncrementalParser::CheckABICompatibility():
  Possible C++ standard library mismatch, compiled with _LIBCPP_VERSION '3700'
  Extraction of runtime standard library version was: ''

****************** CLING ******************
* Type C++ code and press enter to run it *
*             Type .q to exit             *

[cling]$ .q

What should I be setting to allow Cling to run?

Did you install Xcode?
