This seems rather simple, but, how do I INSTALL get_iplayer ver 3.01?. I've downloaded and extracted the files in get_iplayer-3.01.tar.gz to a working directory, in my home directory. But what comes next? I've been unable to find anything that tells you the next step. It's the more galling, that I've done it before, but I now want to put it onto another machine, and I can't recall how I did it the last time. This is a new build, so get_iplayer has not been installed in the earlier versions

Which distro are you using?

Sorry, I'm running Mageia5

Well if there is no package available for your distribution, you can follow the manual install instruction in the wiki.
