Thank you. I'm afraid the version numbers are a bit confusing.

But anyways, I downloaded a static build from 
http://ffmpeg.gusari.org/static/32bit/ as linked on that page and now it 
segments as expected. I only had to add a -map 0 option:

  ./ffmpeg -i udp://239.8.8.8:5000 -acodec copy -map 0 -f segment -segment_time 
60 out%03d.mp3

Thanks,
