Yes, for pkg_install I think I will talk to bapt because he's working
on pkgng so maybe he has a great idea and a better knowledge in C, for
the moment I made some changes in ports/Mk directory but not finished.
I still need to know if a multiple ports could use a same user that
has been added by one of them.

I don't find any good example for this issue.
