I've installed v. 1.15 from source on Ubuntu 12.04. The install did not add any env vars and did not include anything in the .emacs file. I edited .bashrc and used absolute file paths and got some env vars but not CIAOLIBDIR. Also, ciao-mode-init.el does not exist (nor any other file with ciao-mode-init).
Should I be using 1.14? I've done ciaoconfig build, install and user install and most stuff works, but emacs won't recognize Ciao.
