[debug] youtube-dl version 2015.01.04

That's definitely not the last version :), you probably forgot to run make youtube-dl.

Odd. I don't remember needing to run make youtube-dl before, so I just had a nightly cron job doing a git pull && git checkout origin/master in that directory. I'll update it to include the make command. Hadn't hit any issues until it failed for me this morning. Thanks.

I don't know how is your setup, but the youtube-dl file was removed from the repo two years ago (in 5c47fc6).

Note that unless you also need the auxiliary files, you can run make youtube-dl instead of make.
