You're welcome Beñat

Basically DISTVERSION can be used to convert incompatible version strings into
PORTVERSION compatible ones. That is to say, setting DISTVERSION
*automatically* calculates a PORTVERSION value.

See Table 5.2 in
https://www.freebsd.org/doc/en/books/porters-handbook/makefile-distfiles.html

In this case,

DISTVERSION=0.7R6569 make -V PORTVERSION

results in:

PORTVERSION = 0.7.r6569

Testing this value:

pkg version -t 0.7.r6569 0.7.0
<

^--- good (0.7.r6569 is less than future 0.7.0 (true))

Whereas:

pkg version -t 0.7R6569 0.7.0
>

^--- not good (0.7R6569 is greater than future 0.7.0 (false))

So you see why we need to use DISTVERSION, otherwise PORTEPOCH will be needed
in the future.

Since we'll be setting DISTVERSION, you may also need to override DISTFILES in
order to derive the correct distribution file filename.

Hope that helps explain things :)
