[FIXED]Forge src doesn't want to install

So, I have just started learning minecraft modding and I have a problem:

  I'm unable to install Forge src

I've downloaded Build 7.7.1.611, unzipped it, and ran the install.sh file from terminal (I'm on Arch linux 64bit) and the result is

[dusakusD@dlap forge]$ sh install.sh
  File "install.py", line 17
    print '================ Forge ModLoader Setup Start ==================='
                                                                           ^
SyntaxError: invalid syntax

Because it says something about syntax the problem might be caused by python version (I have Python 3.3.1 (default, Apr  6 2013, 19:03:55) [GCC 4.8.0] on linux))

I've also tried to install it on second computer (Ubuntu 12.04 32bit) and everything works fine, but that computer is toooooo slow to work with minecraft (AMD athlon 1.5GHz and Riva TNT2 pro 64)

<----====[ S O L U T I O N ]====---->

I have just found the problem.

The thing is that install script is written for Python 2, so i can't run it using command "python".

When i used "python2"( Python 2.7.4 ) it just:

[dusakusD@dlap forge]$ python2 install.py
================ Forge ModLoader Setup Start ===================
Downloaded mcp7.44.zip
Extracting MCP to '/home/dusakus/MCW/forge/mcp'
Setting up MCP
Backing up commands.py
...

and did all i expected from it

It would be great if someone could put information about python version on the Forge Wiki, or download page.

I'm from Poland, I'm 16 , my English level isn't very good (as you can see above )
