Horizontal scroll bars

[Tom Browder]

I want horizontal scroll bars on my Debian 8 emacs (loaded as a deb
package). I tried this in my init.el file:

;;============
(load "scroll-bar")
(add-to-list 'initial-frame-alist
    '(horizontal-scroll-bars . t)
    )
;;============

and get nothing.

I've tried:

M-x horizontal-scroll-bars-available-p

and get no [no-match]

Do I have to build emacs from source to get it?

Thanks.

Best regards,

-Tom
