After compiling the tarball (default flags) without any problem, most ocaml*
commands works well but "ocamldoc" and "ocamlbrowser" both fail with:

Fatal error: cannot load shared library dllunix
Reason: dllunix.so: cannot open shared object file: No such file or directory

The file "dllunix.so" lays in /usr/lib/ocaml/stublibs, and even with
the former directory in ld.so.conf, the problem persists.

Try to set the OCAMLRUNPARAM environment variable to "v=256" and run
ocamlbrowser. The OCaml runtime system should then tell you what
shared libraries it is trying to load. If these aren't in
/usr/lib/ocaml/stublibs, then perhaps you have an OCAMLLIB or CAMLLIB
environment variable incorrectly set, or shared libraries from a
previous install interfering somehow.

There is no more junk from previous installs. I tried with the
OCAMLRUNPARAM variable, doesn't change much. I'm still said the
dllunix.so is missing (a nice "No such file or directory"). And even
when setting my own OCAMLLIB to something including "/usr/lib/ocaml/
stublibs", it still can't be found.

Soyez précis SVP. Quels sont les messages affichés exactement?

Si nécessaire, ce serait OCAMLLIB=/usr/lib/ocaml qu'il faut mettre.
(Pour qu'il trouve le fichier /usr/lib/ocaml/ld.conf.)

Que contient /usr/lib/ocaml/ld.conf?

Quelle sortie obtenez-vous avec la commande suivante:

strace -e trace=file /usr/bin/ocamlrun /usr/bin/ocamlbrowser

(ça ira plus vite en français, en effet)

Donc, le problème est réglé, merci de votre patience.

Pour la petite histoire: tout cela venait du script d'installation pour
gentoo-linux (que j'étais en train de mettre au point), qui réalise une
"pré-installation" dans un répertoire à part. Et donc le
/usr/lib/ocaml/ld.conf contenait des valeurs complètement inadaptées.

J'ignorais complètement que CAML utilisait un tel fichier, j'aurais pu
chercher longtemps sans votre aide, encore merci.

Et longue vie à OCaml! :)
