[Orgmode] Unable to export to latex

[Antano Solar]

Hi , 

I am using emacs version Version: 22.1+1-2.3

I am using the org-mode that is shipped along with this version of emacs.

Though I am able to export the org-mode files as html and ascii . 

I am unable to export them as latex.

When I type org-export-as- tab i dont see latex in the list.

Being able to export the file as latex will be very useful and from what I read  it is possible.

Any help as to how to get this feature working will be really helpful.

With Regards
