Programming YUN with USB cable

Hi!

Okay, I admit it, I am a newbie. I got my YUN a few weeks back and set up the wifi, it works on the local net. That is great.

I have multiple questions:

[1] I am trying to upload the blink demo program to the YUN with Arduino 1.0.5-r2. Under tools and board, it does not have the YUN listed. Further, it is trying to use a serial port and not the USB.

[2] I used the avr-gcc for the linino piece of the YUN and it cannot read the a.out format. So, I am guessing the compiler is for the atmel piece. What do I need to load to compile code for the linino piece of the yun.

I did search the archives, but it is probably so far in the past that it is not early found.

Many Thanks
