[xcrysden] The rapid screen flickering issue on Mac OS X

[Dan Michael O. Heggø]

The first line in sources.conf should point to the repo root, i.e.
file:///Users/Admin/ports (not including x11/mesa), but I'm not sure
if that's causing your problem. Please reply to me in private if this
is not helping, as I don't think this is very relevant for the other
users on the mailing list.
