I compiled latest pianobar-2011.09.22 in AntiX. I zipped it up and installed it in Macpup 528. I extracted pianobar to /opt. Then symlinked /opt/pianobar-2011.09.22/pianobar (absolute) to /usr/bin.
Just drag and drop it to /usr/bin and pick absolute from menu that opens.
You will need the libao4_1.1.0-1_i386 pet I made in this thread

and the faad2-2.7-v3-wolfe.pet posted in this thread also

Install libao4 and faad2 pet in those links first with petget. Then follow my install instructions above for the zip.

Ignore the opening errors in my below post. They do not effect the use of pianobar.
You'll need a pandora radio account to use this
