'Serial' was not declared in this scope on Arduino 2200 on OS X Mavericks

Using Arduino Programming Questions

I am using Arduino 2200 alpha on Intel Macbook Air, OS X 10.9. I am compiling Marlin firmware for Printrboard (GitHub - ErikZalm/Marlin: Reprap FW with look ahead. SDcard and LCD support. It works on Gen6, Ultimaker, RAMPS and Sanguinololu) on this.
While attempting to compile it, I get the following error

In file included from BlinkM.cpp:5:
Marlin.h: In function 'void serialprintPGM(const char*)':
Marlin.h:91: error: 'Serial' was not declared in this scope

I am unable to compile and flash my firmware because of this. Any help?

Start by getting the latest stable IDE.

The Marlin github looks like has "addon" versions. One for pre-1.0 and post-1.0.

Do as Mark says, get the latest stable version (hint, post-1.0) and the proper "Marlin" files.
