Don't do this with Org from ELPA, I don't think it will work. Try '(package-initialize)' instead.
Seems that the defvar counts for nothing? Perhaps because it's already a defcustom in ob-tangle.el? I don't understand emacs well enough to know, but I will say that inserting a "(require 'ob-tangle)" anywhere before the offending line "solves" the problem.
You are missing the autoloads and the defcustom definitions because the package hasn't been initialized.
