Check environment variables both in terminal and Emacs.

Instead of this I use this (in my ~/.emacs):

(eval-after-load "context"
  '(setq TeX-command-list
     (cons '("ConTeXt" "PATH=/usr/local/opt/context/tex/texmf-linux-64/bin:$PATH context %s"
       TeX-run-command nil t :help "Run context (MarkIV)") TeX-command-list))
)

> And there, I encounter a compilation problem :

and I don't see any errors (note, that in my case the "target" in
"ConTeXt", not "ConTeXt Full").
