Do we really want to use an unofficial site as the only MASTER_SITES?

(In reply to Ting-Wei Lan from comment #4)
osuosl is a mirror for many FOSS projects, and the other one did not have the new version either, 404

I still don't understand why we want to prefer an unofficial site to the official site. I don't think HTTPS can give any extra security when it is not an official site. Also, FreeBSD ports disable certificate verification by default. I guess the only benefit is that it is less likely to be blocked by firewalls.

We have version 1.1.34. The changes in transform.c are in the code. Close - overcome by events.
