The Makefile works on a Mac OSX platform. Tweaks might need to be made for a few compiler flags for your UNIX platform. A make scratch will download monero and boost packages, compile them, and build the six standalone commands below. The Makefile uses tcsh shell commands. Similarly, the BUILD-boost script called by the makefile builds the boost package used by Monero.

The list of package dependencies below is a work-in-progress and is not complete:
