+GC made updates to allow this to build easily on Ubuntu 14.04.2 LTS.
+ - See https://github.com/Proxmark/proxmark3/wiki/Ubuntu%20Linux
+ - Generally speaking, if you're running a "later" Proxmark, installation is very easy.
+ - Run "sudo apt-get install p7zip git build-essential libreadline5 libreadline-dev libusb-0.1-4 libusb-dev libqt4-dev perl pkg-config wget"a
+ - Follow these instructions
+Get devkitARM release 41 from SourceForge (choose either the 64/32 ¿bit depending on your architecture, it is assumed you know how to check and recognize your architecture):
