True enough:

sudo find / -name 'texmf.cnf'
But, then, how comes this file (texmf.cnf) is not found when I run TeXShop in mode XeTeX or XeLaTeX?

The other question is why I seem not to be able to install the latest version of XeTeX "on top" of what exists.
Perhaps it is, actually, but why does it report looking for files in /opt/local when they have been installed in /usr/local ?

==> Il will try to solve this simply, hoping the latest version of xetex is contained in the latest version of MacTeX, which seems natural.

I just added to my profile:
setenv PATH "$PATH":"/usr/local/texlive/2016"

If I understand well, it should solve the problem... but it does not at the moment. 

I'll update my system and restart tomorrow, perhaps that will help.

Question: is there is somewhere a PATH variable specific to TeX (some PATH_TEX or TEX_PATH)?

I did not find a place in TeXShop where I could specify which instance of TeXlive it should use.
Perhaps it is still using texlive/2011 or texlive/2015?
Tomorrow (too late now), I'll remove the older versions of TeXlive and the separate folder used to try to install semtex 0.99993 separately.
