Let me start by saying when we pull the source code (master) with:

   git clone https://github.com/POV-Ray/povray.git

what we get for README* files in the unix directory is a bit confusing. 

README -> I believe this is an old linux build from source instruction file.

README.MD -> This is the valid one I think and "probably" some developer 
script is/was supposed to replace the README above with it before ship. 
This README.MD is OK except at the bottom where the dependencies are 
listed. For the "boost" libraries it has :


which is incorrect for debian based systems and should be :


or perhaps the following would work (not tried it) :


Aside: I think libboost.dev - which exists - is needed for developing 
individual boost libraries and so not what povray needs.

README.unix -> Old 3.6 linux install information along with a some 
information that might still be useful.
README.bin -> For the days when some linux binaries were provided I guess.

------------------------------- On Ubuntu 14.04.01

The master or 3.7.1-alpha.8344733 branch worked fine, while the
3.7-stable branch still required the extra:

  LIBS="-lboost_system -lboost_thread"

on the ./configure command. The ./prebuild is also noisier warning wise 
with the stable version, but worked for me.

A surprise for me is that the 3.7.1-alpha.8344733 version of povray 
--benchmark ran about 19% slower than the stable or 3.7.0 version in 
several trials. Expected? There are additional original rays shot in the 
master branch - much less than 19% more - but maybe these extra rays 
"heavy ones" compute wise?
