Sorry, I mistyped slightly.  It should be incomplete shadowing; I
explain below.

Are there any system Org libraries *not* shadowed?  That would be make
this a typical mixed install problem.  All the old libraries should be
shadowed by the newer vesion.  So if "new" is a superset, you are good.
If there is an overlap, but not all, something is wrong.

Indeed.  My Org as shipped with Emacs is 8.2.5.c (I updated yesterday).
Where as my Org from git is 8.2.5f (release_8.2.5f-511-gbf304c).  I
updated Org yesterday.

$ git describe
release_8.2.5f-511-gbf304c3

I do that myself.

$ git pull --rebase
$ make compile autoloads info # similar to update, I use this for historical reasons

Then point to the path in my init.el.  This last bit, you should do very
early in your init file.  Here is my setup to give you an idea (see line
18): <https://github.com/suvayu/.emacs.d/blob/master/init.el>.  You can
ignore the kill-old-org bit, it is experimental.

Well I think now there is a target (make uncompiled) just to make it
easier to run from sources.  Many of the devs prefer this, creates nicer
backtraces.
