[OS X Emacs] latex + dvips + ps2pdf from Aquamacs

Hi Ettore,

Sorry I've not been able to answer earlier.

Indeed, my ~/.zprofile and  ~/.zshrc are interfering and messing up the
PATH environment variable, at least in Aquamacs, hopefully not more.

I upgraded to Catalina macOS this Summer, and, as prompted by it, I moved
from bash to zsh. I created / exported ~/.zprofile and  ~/.zshrc from the
corresponding ones of bash. I followed whatever the Mac's Catalina prompted
me for, read Apple Support:
https://support.apple.com/en-us/HT208050
and some from the zsh website, to which I got from the "man zsh''. O
bviously, I didn't get enough details.

Here are some tests I've done and the dot files you think would be useful.
I would like to get help, feedback, and know what and how. I hope that the
upper settings are as they have been from Apple, because I have never
attempted to modify them, at least not deliberately.

I've been learning these days with all this. Thanks for your help!
