Good shot, thank you !
with ocamlobjinfo, i have :
    2a19929a535447ed0c8fc58ae3adc1a0    Unix
    2a19929a535447ed0c8fc58ae3adc1a0    Unix

When i make the webserver with ocamlfind, ocamlc launchs :

+ /Developer/usr/bin/clang -o 'cwbtop'

In fact, it works well with ocamlopt as you said. It's realy a problem of
double link

I searched a bit around this problem, but i don't find a way to fix it :
the clang command line always call unix two times...
(But i can test with a native version it's a beginning)
