Hehe, actually i just found the following in my .gnus (seem to be time for a
bit of housework ;)
,----
| ;; Lorsqu'un article n'est plus disponible dans le serveur NNTP, on utilise
| ;; google.com
| ;; Message-id : <m3wurdqusg.fsf@fermat.mts.jhu.edu>
| ;; This snippet comes from the info docs Gnus->Finding the Parent.
| (setq gnus-refer-article-method
|       '(current                
|               (nnweb "google" (nnweb-type google))))
| (setq mm-url-use-external t
|       mm-url-arguments
|        `("--silent"
|          ,(concat "-A Mozilla/5.0 (Windows; U; Windows NT 5.0; "
|       
|             "en-US; rv:1.3a) Gecko/20021207 Phoenix/0.5"))
|        mm-url-program "curl")
`----
So it gives it a try with curl, not internal url.el...

As i sometimes use Gnus on  non-Unix systems that might not provide curl nor
wget, i am considering a conditional define of mm-url-use-external.
Is there a function like  file-exists-p or file-executable-p that can search
the PATH ?

Okay,  i have  re-read your  explanation again,  also with  some RTFM  and i
understand more how it works.

I have also heard about my ISP  news gateway that it is composed of multiple
servers  (all  bounded to  the  same  address so  you  can't  select one  in
particular) and that sometimes the same message can't be reached for a while
in all the servers... So it might be an ISP problem.

So I will add gmane to the list to see if the problem remains.

Thank you for your infos :)
