That's singe-worthy right there. That release is almost 6 years old.
We've done 31 releases since then.

The first thing would be to try a newer version of curl and see if the
problem still exists. If it's a curl problem, there's an excellent
chance that it has already been fixed.

-v should tell you enough clues about where the problem may be. You didn't
send us the log, so it's hard to speculate about it. You can also try
doing the simplest curl transfer possible (curl URL > file) and see if
that succeeds, or try another program to try to determine if it's a server
bug of some sort.
