Install Lame MP3 encoder

Hi,
Can someone please tell me how to install the Lame MP3 encoder so that AF can use it?
The Lame folder is in my Downloads folder. Apparently I should use a Terminal command, but I can’t get it to work. I’m stuck at <sudo cp /Volumes/lame/lame /usr/local/bin/lame>
There used to be an mp3 encoder in the AF extras folder, but it’s not there anymore…

Thanks!

You could potentially try downloading Lame MP3 encoder separately?
