Ok, i don't believe this would be such a problem, but anyway, that is
why i was thinking of doing a version changing script, which would wrap
all the update-alternative calls. This way, the user would only have to
call switch_ocaml <version_number> and automatically the right
alternatives for the <version_number> version of ocaml would be choosen,
It would be nicer if update_alternative supported alternative
meta-packages or something such though.

Err, i think you wanted to say that is why gcc don't use alternatives
but simple symlinks ?

Mmm, ok. But the idea was _not_ to rebuild older versions of ocaml when
i upload the new one. Let me think more about it.
