[O] Compilation problem

[Alan Schmitt]

Hello,

I cannot compile the current version of org-mode (from git): something
fails during testing:

make test-dirty
install -m 755 -d /var/folders/68/fvntfrw92y50gkk_67rkhsfw0000gn/T//tmp-orgtest
TMPDIR=/var/folders/68/fvntfrw92y50gkk_67rkhsfw0000gn/T//tmp-orgtest 
/Applications/Emacs.app/Contents/MacOS/Emacs -batch -Q  --eval '(add-to-list 
'"'"'load-path "./lisp")' --eval '(add-to-list '"'"'load-path "./testing")'  -l 
org-install.el -l testing/org-test.el --eval '(require '"'"'ob-awk)' --eval 
'(require '"'"'ob-C)' --eval '(require '"'"'ob-fortran)' --eval '(require 
'"'"'ob-maxima)' --eval '(require '"'"'ob-lilypond)' --eval '(require 
'"'"'ob-octave)' --eval '(require '"'"'ob-python)' --eval '(require 
'"'"'ob-sh)'  --eval '(setq org-confirm-babel-evaluate nil)' -f 
org-test-run-batch-tests
Symbol's function definition is void: org-export-define-backend
make[1]: *** [test-dirty] Error 255

Here is my local.mk

EMACS=/Applications/Emacs.app/Contents/MacOS/Emacs
prefix=/Users/schmitta/.emacs.d/vendor
SUDO =
ORG_ADD_CONTRIB=org-checklist org-export org-e-*
up2::

Is this a (known) bug?
