Hi, all.

I was trying out feed.el today, and I've got an error that I don't
understand.

Following the docs, I put this in my .emacs:

(setq org-feed-alist
          '(("Slashdot"
         "http://rss.slashdot.org/Slashdot/slashdot"
             "~/org/feeds.org" "Slashdot Entries")))

I created a file in ~/org called feeds.org and in that file did C-c C-x g.
A headline for Slashdot Entries appeared.  But when I do C-c C-x g on that
entry I get the following message:  "Symbol's value as variable is void:
xml-entity-alist"

Nowhere do I find any information about setting that variable.  Any ideas?
(I'm using the latest development version of Org, compiled from git sources
today).

Thanks,
Mark
