Hi Gus:
All above are sound and precious suggestions. I took force from your
mail. Although the flag "-openmpi" and "ifort" for the compiler
worked nicely with me at the time of amd64 etch, I'll try the full
paths and the names you suggest.

As to intel 11, I made a deb package with program "alien". Did not
install. A fixing is required. There is a young smart colleague in
Australia who is modifying his script to fix the deb package (if you
are interested at all in deb packages, I'll keep you informed; his
script for versions 9 and 10 worked nicely).

I am getting very strange results, such as files that are not found
(while they are where expected and the env variables are correct in
the cheat between the message passing interface and amber. One thing:
I have noticed on several occasions that if the situation is not
perfectly correct from the unix point of view, debian refused to do.
It has recently occurred with DOT2, who was used with Mac unix, but
debian found incorrect stuff (the installation code was corrected by
very kind DOT2 people and a paper is now on the web on the ACS

I'll try to reorganize the situation and when the problems are clear
may be I'll ask again advice here with the information you suggested.
