[Orgmode] Tangling

[Andrea Crotti]

So for my presentation I'm preparing a minimal emacs configuration which
will have
- org-mode/babel
- python mode
- yasnippet/auto complete 

And it will be everything here
http://github.com/AndreaCrotti/Org-mode-notes

I'm running
Org-mode version 6.34trans
on
GNU Emacs 23.1.50.1
(i386-apple-darwin9.8.0, NS apple-appkit-949.54) of 2009-09-16 on neutron.local

But I don't know why I'm not able to tangle anything and then load the
elisp code from an org-mode file.

--8<---------------cut here---------------start------------->8---
ELISP> (org-babel-load-file "/Users/andrea/Documents/pycon/miniconf.org")
*** Eval error ***  No buffer named miniconf.org
--8<---------------cut here---------------end--------------->8---

But the file is actually there, or like this
--8<---------------cut here---------------start------------->8---
ELISP> (org-babel-tangle "/Users/andrea/Documents/pycon/miniconf.org")
nil
--8<---------------cut here---------------end--------------->8---

And it doesn't export any source even if it looks something like this

--8<---------------cut here---------------start------------->8---
* Org mode
** Clock configuration
#+begin_src elisp :tangle yes
;; Clock configuration
(setq org-clock-persist t)
(org-clock-persistence-insinuate)
#+end_src
--8<---------------cut here---------------end--------------->8---

Any idea?
