Beamer presentation using new exporter

Beamer presentation using new exporter

I am finally trying to use the new exporter to create a beamer
presentation. I started with a simple orgmode file. My file is as
follows:

#+STARTUP: hidestars
#+TITLE: Title
#+AUTHOR: My name
#+OPTIONS: H:2 toc:nil
#+E-MAIL: username@email.org
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [presentation]
#+BEAMER_THEME: default
#+COLUMNS: %45ITEM %10BEAMER_env(Env) %10BEAMER_act(Act) %4BEAMER_col(Col) %8BEAMER_opt(Opt)
#+PROPERTY: BEAMER_col_ALL 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0.0 :ETC
#+OPTIONS: H:2

* Introduction

------cut here--------


The log file showing the error is attached herewith.

I am using org-version 7.9.3f.

Will be grateful if somebody could explain why am I getting an error.

This is unrelated to your problem, but it should be "#+EMAIL:"

> #+LaTeX_CLASS: beamer

"beamer" class is probably not defined in `org-latex-classes', hence
your problem.

Note the name of the class doesn't matter, but it should be associated
to a "beamer" documentclass anyway, unless you have loaded a specific
package for Beamer article mode.

I shifted from the elpa version to the version downloaded using git
repository. But I still get this error. org-version says:

Org-mode version 7.9.3f (release_7.9.3f-1360-g2d3add @
/home/vikas/lisp/org-mode/lisp/)

Without configuration, export framework and default back-ends are not
loaded along with Org, but the first you need them (by calling an
autoloaded function).

You may be trying to modify `org-latex-classes' before having `ox-latex'
loaded.

You can either explicitly (require 'ox-latex) before that, which will
load all export framework along with Org, or use the following
construct:

  (eval-after-load 'ox-latex
    '(add-to-list ...))

In the latter case, you still get framework loaded only when you need it
the first time.

I don't know why this is turning out to be so difficult. I have got
ox-latex loaded, and have defined beamer class in org-latex-classes. 

But I still get an error with the simple org file that I am trying to
export. I am attaching both the org file, and the log of errors thrown
by pdftex. 

Will be grateful if somebody could explain what may be wrong now. This
is turning out to be quite frustrating.

You mean `ox-beamer' right?

It looks like you're encountering the same problem. How do you export
your document?

For example "C-c C-e l O" should use Beamer back-end. If this isn't
a valid combination, you didn't load beamer backend. Tweak
`org-export-backends' to fix it.
