Thanks for the reply!

I have been trying to compile the ocaml-autobuild but it seem that it do
not works.

I have done make/(make test) after/before apply the patch and I obtain
the following error:
        
$ make test
ocamlbuild -classic-display ocaml-autobuild.otarget

src/base/BaseSys.ml > src/base/BaseSys.ml.depends
sh: Illegal option -p
Preprocessing error on file src/base/BaseSys.ml
Command exited with code 2.
make: *** [all] Error 10

Can some one help me?

I downloaded the tree with 'wget -r' which did not did this very smooth.
I have uploaded a tar version  of it (without to apply the patch).

numbers with me there is no problem ;-)
