Waf

It is best you install waf by just downloading it from the Waf project website:

http://code.google.com/p/waf/

Waf is a Python program so you will also need to have a current Python version installed and in your path.

I download the latest "run from writable folder" version named single waf file from http://code.google.com/p/waf/downloads/list to $HOME/bin and symlink it to waf. The directory $HOME/bin is in my path.

$ cd $HOME/bin
$ curl http://waf.googlecode.com/files/waf-1.7.9 > waf-1.7.9
