Ok, I just found out that it works only when using the shell from my graphical 
environment (KDE).

Login from a text console or SSH does not work. But .zshenv is invoked in any 
case. I suspect that the two latter cases (text + SSH) are login shells and 
/etc/profile is evaluated. This file simply sets and not append/prepend to a 
existing PATH.

I concur.

It works (the PATH setting I did in .zshenv is there). But as you have guessed 
it fucks up my environment ;-)

I changed my /etc/profile from

PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin"

to

PATH="$PATH:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin"

Any potential problems with that?

Thanks!
