Thank you for reply.
I have noticed your comment in https://github.com/boostorg/build/issues/308:

... and added project definition to my Jamroot.jam that was previously empty:
project cvboost : default-build debug;

That solved the problem however I am not 100% sure why.
For your information, difference in properties (site-config.jam vs toolset=)
before making changes to Jamroot was:
<toolset-clang:platform>darwin <toolset-clang:version>4.2.1
The latter 2 was added when invoking b2 with toolset=clang.
