I have cloned the repo, and installed boost and boost-build using Homebrew on the Mac. I copied the configuration files as instructed, but I am getting this error with b2 release:

~/src/owlcpp $ b2 release

As far as I can tell, b2 seems not to be satisfied with having the boost libraries pre-built -- it also wants their jamfiles. These don't seem to be distributed with the pre-built boost library as supplied by Homebrew. Shouldn't owlcpp be able to build itself without having to build the boost libraries, as well?
