On the other, we are "virtually" at 90% coverage if we would delete the old notebook: http://trac.sagemath.org/sage_trac/ticket/11409

Re: Sage 5.2 released  Simon King  8/14/12 2:01 AM  Hi Leif,
As I wrote in my previous post, this is what I tried. Slight problem was: Since Python has not been available, ./sage i openssl could not download the openssl spkg. But I downloaded it manually, installed it, and did make. And 5 minutes ago, I found that it indeed worked. The question arises whether openssl should be a standard spkg that is installed if the openssl headers can not be found on the system. That would be similar to the gcc spkg, which is standard but is only installed if the gcc found on the machine is the wrong version (or the user asks for its installation). Cheers, Simon

If we ship OpenSSL with Sage, we *certainly* violate the GPL. IMHO, we might still be violating the GPL with the optional package, but that's not so clear. 
Re: Sage 5.2 released  Volker Braun  8/15/12 6:49 AM  Really we should get sage i to work without ssl as long as you don't download from a https url. In fact, nothing in Sage should depend on ssl except for the notebook. For the record, the next Sage version checks for ssl headers/libraries in prereq and will recommend that you install it via your package manager before the compilation starts.
