Massive download from github.com

I have followed the instructions in the Playground for installing the latest software from github.com for my gentoo system.

Why is the download from github.com so mine-bogglingle huge? It's 750MB and counting!

Shocked...
Jim

What download? Link please?

It said to put the following in the layman directory:

When I ran ‘emerge arduino’, a lot of java stuff was built, then:

Out of all of that, only 8.6MB of space is used in /usr/share/arduino-0021.

I found the 'arduino' executable at /usr/share/arduino-0021/arduino. When I started it, the first thing I saw was a window saying there was a newer version availale (1.0.1). I thought what I got from github.com was supposed to be the latest.

What link at Github.com?

Do you mean this?

That's hardly recent.
