Debugging CGAL problem en route to brew install postgis

README.md

I was trying to brew install postgis and got an error on the cgal dependency.

It looks like maybe it has to do with boost, but according to the CGAL manual, I have a suitable Boost version (>1.39)

brew info boost

$ brew info boost
