If it works in Terminal I'm mystified; Mark Wieder may have a tip for that.

Have you tested it with libURL?  For HTTP/HTTPS it shouldn't be 
necessary to use curl or other outside programs.

FWIW, I did some testing with wget yesterday (not the same as curl, but 
often considered a bit lighter), and I found that the overhead of 
instantiating the terminal session with shell meant that using libURL 
was about 20% faster overall for downloading a 1MB binary data file.
