Sorry for the late reply, but hopefully it's still useful to people looking for get_iplayer:
This works for me on a fresh install of mageia 1 (32-bit live cd, KDE).
Go to install/remove software and enable the tainted repositories (Options -> Media Manager -> Check the box to enable Mirror List Tainted Release, and Mirror List Tainted Updates)
Reload the package list (File -> Reload Package List)
Search for
rtmpdump and select it (it probably doesn't matter if you choose the tainted one or not, but I chose the tainted one)
Search for
vlc or and select it. mplayer also works, but if you use either one of these media players, it
must be from the tainted repos for the audio to work. The version number in the 'release' column will end in 'tainted'.
Search for
ffmpeg and uncheck the one currently installed, replacing it with the version from the tainted repos.
Download get_iplayer from here (currently the most recent is get_iplayer-2.80.tar.gz)
ftp://ftp.infradead.org/pub/get_iplayer/Extract the get_iplayer tar.gz file in your home directory.
You might need to make the script executable (I didn't)
cd into the folder and type
chmod +x ./get_iplayer
Then try running it:
e.g.
./get_iplayer --modes flashvhigh --pid b014kndt
