Thank you Marius.

Previously I do not have a password, so I just typed enter three times, and it did not work.

Now I set my password, and...it works...

Because my mac OS does not have a password, so I just typed 'enter'. However,

Ming, **please** "reply-all" so that others can follow along and not answer previously answered questions.  Also type you response at the **end** of the email so that those arriving later can follow the discussion.  I've responded further at the bottom.

Ok.  To start I recommend you install a package management system.  Fink and Macports are good choices which I have experience with.  Homebrew is also available, but I've never used it.  I'm no longer building the development sources using Fink, but can help you with Macports.

        http://wiki.octave.org/Octave_for_MacOS_X#MacPorts

After installing Macports, ...

        sudo port install octave-devel +atlas+fltk+gcc47
        sudo port install mercurial
        sudo port install autoconf
        sudo port install automake
        sudo port install flex

The install of octave-devel will provide all of Octave's dependencies.  After installing mercurial, autoconf and automake, you'll be ready to follow the instructions at the link below.

Ming,

Your login password will do nicely. 

Set?

You should not have to "set" a password. 

Did you set up a root password? Not a good idea under Mac OS X. 

Any account that has administrative privileges can run sudo with its login password.
