Installing Octave on a MacBook Pro

[Michael Farmer]

Hi,

I have a MacBook Pro ( mid 2010, OS X Version 10.8.3, 2.53GHz, i5 processor, 4GB RAM) and have been trying to install Octave. I am not a computer expert but have been following the instructions given in the "Octave for MacOS X " section of (http://wiki.octave.org/Octave_for_MacOS_X). I believe I have XCode installed, at least it appears  in my applications list and can be opened although I have never used it in anger, and have tried following the instructions given under MacPorts using the Terminal application. I keep getting the following messages:-

Warning: The Command Line Tools for Xcode don't appear to be installed; most ports will likely fail to build.

Warning: See http://guide.macports.org/chunked/installing.xcode.html for more information.

Michael-Farmers-MacBook-Pro:~ michaelfarmer$ 

I am obviously doing something wrong, or have failed to install something correctly, but with my limited knowledge I cannot fathom what. Most of the reported problems shown above don't mean much to me. I am not a "Power user" but simply want to explore Octave and maybe progress some work I did with MATLAB before I retired, just for interest. 

Can anybody point me in the right direction, please??

Thanks,

Mick Farmer
