Install octave on Slackware64 14.1

After several days failed trying to build and install octave with error "can not found tex package" eventhough I've tetex on my slackware, Finally I've found a solution.

Here is the step:
1. Remove tetex and tetex-doc packages from Slackware
2. Download and install texlive from Slackbuilds.org. Don't forget the require packages; texi2html and libsigsegv.
3. Install octave.
4. Finish


Now I can resume my free machine learning lesson...:D
