This is an rtmp video, so it's not as easy, but possible. Here's a step-by-step to download it:

First, I'm afraid I broke youtube rtmp downloading in the newest version. Either download my updated fork or apply this patch
_{(@rg3, could you cherry-pick it, minus the print? Looks like youtube sends a useless url_encoded_fmt_stream_map for rtmp streams. We need tests for that ;) )}.

Then, download, compile and install the newest rtmpdump:

git clone git://git.ffmpeg.org/rtmpdump
(cd rtmpdump && make && sudo make install)

Check that everything worked by typing rtmpdump. This should say RTMPDump v2.4. Now, go ahead and download the video with youtube-dl. There won't be a download status output (something we should work on), but in traditional UNIX fashion, no output is a good sign in this case.

One more caveat: If this fails with a Segmentation Fault, you have librtmp installed on your system. Instead of overwriting it, you can also use

LD_PRELOAD=rtmpdump/librtmp/librtmp.so.0 youtube-dl -t 'http://www.youtube.com/watch?v=pZZ60jrw6cg'

to prefer the librtmpdump.so.0 file from the downloaded development version over your distribution's one.
