Hi all, with the current HEAD (commit 0202adb1c02908a75a7845438381e40d811fd99a) from master I get an error during the export of one of my files complaining about an undefined my-filt function.
Replacing org-flet with flet in ob-comint.el (line 78) introduces a compiler warning, but solves the problem. I am on emacs 24.1.50.1. Regards, Andreas
