Dear Ivan,

It gets even weirder (it begins to look as the start of a summertime 
thriller). *Before* seeing your last reply, I saw that sage 5.10 was out 
and installed it on my "big desktop" machine (compilation from sources, 
installation of the new R spkg and related patch, installation of 
database_gap 4.5.7 as recommended by the readme, and of dot2tex and 
sage_mode).

This time, even after suppression of the .sage directory, it doesn't even 
work : M-x sage succeeds, giving me a prompt ; but typesetting doesn't 
work. Asking for 2+2 gives me :
Typesetting \newcommand{\Bold}[1]{\mathbf{#1}}4...
[ BTW : I had to type this in this mail ; copy-and-paste from the emacs 
wondow gives this :
<html><script 
type="math/tex">\newcommand{\Bold}[1]{\mathbf{#1}}4</script></html>
]
in the *SAGE-main* buffer and the following messages in the *Messages* 
buffer :
Creation of `/home/charpent/.sage/tmp/emacs20421oDo' failed: Creating 
directory: aucun fichier ou dossier de ce type, 
/home/charpent/.sage/tmp/emacs20421oDo
error in process filter: sage-view-process-overlay: Opening output file: 
aucun fichier ou dossier de ce type, 
/home/charpent/.sage/tmp/emacs20421oDo/sage-view_20421bAW.tex
error in process filter: Opening output file: aucun fichier ou dossier de 
ce type, /home/charpent/.sage/tmp/emacs20421oDo/sage-view_20421bAW.tex

Now for your questions : I cannot access tonight my "small desktop" 
machine, which still has 5.9 and exhibits the original problem : it will 
have to wait for tomorrow afternoon... Stay tuned !

Thank you very much for your attention,

                                                                  Emmanuel
