[Orgmode] Problem with 6.09a org-agenda-list

[Bart Parliman]

After upgrading from 6.02 to 6.09a on emacs 22.2 I'm having 
trouble running org-agenda-list and am seeing...

  Symbol's function definition is void: adjoin

As far as I can tell, the agenda appears complete.

FWIW, my lisp knowledge is weak.  It looks like the symbol is 
defined in the common lisp area.  I'm assuming that it's not 
getting loaded and my simple attempts at trying to do that didn't 
help (not a surprise).

FWIW, some searching brought up a patch from this past July...

http://article.gmane.org/gmane.emacs.orgmode/7545

After undoing the patch it "works", but I'm assuming that's 
probably not the right thing to do.

Thanks,
Bart
