Recently I decided to give Rant a go having heard that it was better than Rake. Installing it on Ubuntu is a bit of a mission (well not really) - as the rant package only very recently made it into Debian Unstable, it isn't in the Ubuntu store just yet so apt-get doesn't do the job. Taking life in hands I downloaded and installed the Debian Unstable package and... it worked fine. The only problem is that there is no Bash completion script in the distribution. Easy to fix, write one. Having done one for SCons recently, taking the script from the rake package and amending it for Rant was relatively trivial. You can find it here.
