Here's a hint for folks using the new libemacs with gnu-apl-mode: You *must* reinstall the gnu-apl-mode native library every time after installing APL.
For example: $ cd ~/gnu-apl $ svn update --accept tf $ make $ sudo make install $ cd ~/gnu-apl-mode/native $ # -- Optionally: pull and compile $ # git pull $ # make $ # -- Always reinstall, even if you don't recompile $ sudo make install
