I successfully upgraded Org mode to version 8 by following these[1] instructions. I am now trying to repeat this on a Mac OS X system. After "M-x list-packages", Emacs connects to elpa.gnu.org and then to orgmode.org, but reports that it is unable to connect to orgmode.org, and presents a list of the packages from GNU only (no upgrade is available for org). Navigating to the Org mode repository directly works, so the site is online. I am using a modified version of Emacs[2] with various packages pre-installed[3], which has Org mode version 7.9.3f.
