Since it is added to the load-path during compile it might have
undesirable side-effects if an older org-mode resides at that path.

But, I'm now getting these errors too since I have started Emacs
freshly.  The offending commit is 9ff7f80f51a by Eric Schulte, where he
wraps the defvar definition into eval-when-compile.  This change defines
the variable during compile and gets rid of that error, but then it is
not defined when loading org-mode the first time.  If you do an
org-reload this is rectified (which is why I didn't see the error
yesterday.

The original error during compile-time comes from using the variable in
a macro expansion.  I don't think this is the right thing to do since we
would not want to expand the variable at compile time (it would not be
variable anymore after compilation).  The attached patch seems to
correct this for me.

Subject: [PATCH] Prevent runtime error introduced by commit 9ff7f80f51a

    * lisp/ob.el (defvar): revert wrapping into eval-when-compile since it
      makes the variable non-existent during initial load.
    * lisp/ob.el (org-babel-map-inline-src-blocks): un-comma use of
      variable org-babel-inline-src-block-regexp, since we don't want
      to expand it at compile-time

Let us know if that fixes things for you and I'll let Eric decide if he
pushes that patch or something different, depending on what he really
wanted to do.

Achim.
