FreeBSD 10.2 package not installing - pkg add - NO MANIFEST FOUND?

Question

FreeBSD

Hello.
Sobsvtenno subject.
I'm trying to file squid 4.0:

pkg add http://www.squid-cache.org/Versions/v4/squid-4.0.1-20151021-r14361-RELEASENOTES.html

Writes No manifest found.
Tell me how and what to use? In ports version 3.5.10, I do not want it.

It turns out that these are the source codes, I'm just weak in vryah so far. I compile-compile from sources for this article admi0n.blogspot.ru/2011/03/targz.html
