Well, it seems that I have a much simpler problem (and it is not related to
camlp4of specifically): the only thing I'm missing is a '-syntax camlp4o'
when compiling the library. Indeed, adding:

<src/syntax/*>: syntax_camlp4o

at the end of _tags fixes the problem. I must have forgotten an option in
the _oasis file, but I can't see which. Anyway, many thanks William !
