I'm glad it works for you though

>> export PATH=$PATH:/home/aragorn/bin

don't understand how these lines help you. As you said you were able to
typeset a sample document in terminal, so all settings in terminal (bash
I presume) were fine, especially taking into account that 'setuptex'
exports only PATH variable with correct path for Standalone ConTeXt.
They might change environment from which Emacs is launched but again,
you use full path to run context so they must be irrelevant here.

In one of previous messages
(https://www.mail-archive.com/ntg-context@ntg.nl/msg88742.html) you told
that you use Archlinux, did you install texlive-* packages? Did you
update your system? I use Archlinux and have not only ConTeXt
standalone/suite and TeX Live (TUG) installed but also I have installed
texlive-* packages from distribution repository and don't have any
problem with the example either in terminal or Emacs(+AUCTeX), I suspect
that your Emacs configuration might be the cause of the problem.

Why you insist on using hooks when you specify in full the custom
target? Just add this option to the custom target:

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