Dynlink ocamlfind problem

[Dmitriy Kargapolov <dmitriy.kargapolov@gmail.com>]

Hi All,
This already was discussed but in context of Win32/Cygwin.
I found similar behaviour in Unix environment.
Playing with ocamlfind command I found that option "-package dynlink"
didn't add anything to the generated build command, but other
packages, extlib for example, did that.
Looks like problem with ocamlfind.

test1:

$ ocamlfind ocamlopt -verbose -o test test.ml -linkpkg
Effective set of compiler predicates: autolink,native
+ ocamlopt.opt -verbose -o test test.ml
+ as -o 'test.o' '/tmp/camlasm635817.s'

'/usr/lib/ocaml/std_exit.o' 'test.o' '/usr/lib/ocaml/stdlib.a'

test2:

$ ocamlfind ocamlopt -verbose -o test test.ml -linkpkg -package dynlink

Note that I have this dynlink installed:
