 Looks like sourceforge downloads are now redirecting http to https. From a
 failed build on 10.5:

 To avoid redirects, we need to change the sourceforge fetch group's
 protocol from http to https.

 The fact that the ssl certificate they're using is too modern for 10.5 to
 understand is already covered by other tickets.
