I think I was not very clear:

1) First, as root (it means, using "su"), you need install sudo (as package
or port)
2) Again, as root (it means, using "su") you must edit
/usr/local/etc/sudoers (if using vim/vi, you must save the files forcely, I
mean, wq! in the end)  adding which users can be sudo
3) As a user included in sudoers file, you can type any command, like, sudo
mkdir /usr/local/etc/test: system will ask the password for the user (not
more as root). In the first time, you (as user) must agree with terms)

I think now, I was more didatic.
