I'm running 2.8.2 on Mac and 2.8.0 on Linux.  So I downloaded / built / installed the latest 2.8.3 source on Linux.

Now I'm getting error messages indicating libcurl does not support HTTPS:

  unsupported protocol

So I double checked that I have the latest libcurl3 installed, and that I can hit that https url using curl on the command line (where I find that sourceforge is redirecting).  So I'm stumped.  Please advise.
