Difficult in installing PyPy3 2.1 Beta 1 on ubuntu

I downloaded the PyPy3 2.1 Beta 1 prebuilt binary file " https://bitbucket.org/pypy/pypy/downloads/pypy-2.1-linux64.tar.bz2" and unpack it. But When I run pypy in the bin directory, I was given an error: "The program 'pypy' is currently not installed. You can install it by typing: ..." instead of the success message in http://doc.pypy.org/en/latest/getting-started.html#id14. Actually this webpage says "PyPy is ready to be executed as soon as you unpack the tarball or the zip file, with no need to install it in any specific location:" Is there any particular install instruction for PyPy3 2.1 Beta 1 on Ubuntu as opposed to the web? Do I have to create a symlink? Btw, I'm using Ubuntu 13.04, is this mismatch of Ubuntu version the reason for the installation failure? Thank you.

What are you doing exactly when you say "When I run pypy in the bin directory" ? what's your PATH ? Did you cd into bin and run it as ./pypy ? -- Vincent Legoll
