SSL: CERTIFICATE_VERIFY_FAILED on OS X 10.10.3

[aisrael]

youtube-dl: stable 2015.04.03 (bottled), HEAD (installed via Homebrew) was working great until yesterday, then I upgraded to OS X Yosemite 10.10.3 overnight.

Now, I keep getting

ERROR: Unable to download webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate 
verify failed (_ssl.c:581)> (caused by URLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] 
certificate verify failed (_ssl.c:581)'),))

A workaround is to use the --no-check-certificate flag.

Pretty sure this isn't youtube-dl's fault (OS X 10.10.3 probably trashed some roots or CA certificate files) but I'm putting it here so someone with more time and understanding than me can maybe post a proper solution, and so others can find it here, too.

Please post the full verbose log with --verbose option

Possibly a duplicate of #5317. Could you try the workaround provided by @izzyleung in #5317 (comment)?

(Apologies for the URL ;) )

Got it, tried the workaround in #5317 (comment).

The following worked:

SSL_CERT_FILE=/Users/aisrael/curl-7.41.0/lib/ca-bundle.crt youtube-dl --verbose https://www.youtube.com/watch?v=dQw4w9WgXcQ

And yields (for reference):
