In particular (comparing the org-plus-contrib-20150202 package against today's 
http://orgmode.org/cgit.cgi/org-mode.git/tree/contrib/lisp):

htmlize.el
ob-stata.el
org-colview-xemacs.el  (not that I really care about this one)
org-download.el
org-ebib.el
org-effectiveness.el
org-eldoc.el
org-eww.el
org-index.el
org-license.el
org-passwords.el
orgtbl-sqlinsert.el
ox-extra.el
ox-gfm.el


At the very least, please ensure that htmlize.el gets packaged.
