You get an error message because outlinetext doesn’t work.

\starttext

\startMPcode
    draw outlinetext.f

Hello,
Sorry to insist, but could anyone help me understand the problem I'm having in using Emacs with standalone context ?
The following file compiles perfectly from a terminal :

/home/aragorn/texlive/2018/bin/x86_64-linux/context  test.tex

/home/aragorn/context/tex/texmf-linux-64/bin/context  test.tex (latest beta)

With Emacs, it compiles perfectly if you use the 2018 texlive context binary.

If I want to use the latest beta context binary, I need to add this to my ~/.emacs file :

(setenv "PATH" "/home/aragorn/context/tex/texmf-linux-64/bin/:$PATH" t)

And there, I encounter a compilation problem :

Running `ConTeXt Full' on `pouf' with ``context --purgeall --nonstop pouf.tex''resolvers       | trees | analyzing 'home:texmf'
