Make shebang line more portable (don't invoke wrong python version by mistake)

[0ion9]

On systems, such as Arch Linux, where Python 2 and 3 can coexist, it's a mistake to refer directly to the 'python' binary in a shebang: this will not always point at Python 2. On Arch for example, it points at Python 3, which 'rip' is not compatible with.

However, 'python2' can be relied on to always point at Python 2.x :) See http://www.python.org/dev/peps/pep-0394/

With that change to the shebang line, I was able to successfully install 'rip' on (Lighttpd + mod_cgi / Arch Linux x86_64)

I just tried "python2" on my server and got

zsh: command not found: python2

$ ls /usr/bin/python*
/usr/bin/python /usr/bin/python2.5 /usr/bin/python2.5-config /usr/bin/python2.6 /usr/bin/python2.6-config /usr/bin/python-config

I could manually setup a symlink for 'python2' on my box, but then others with my same setup would too.

I have updated the installation wiki with solutions for this case.

Marking WontFix 'cause I'm lazy. Sorry!

What about python2.7 ?

As shown above, python2.7 is not on my box. I'm not going to make changes that will break my own copy.

I may look into supporting 3.0 (Shouldn't be too hard, not many print statements).
