call wp_enqueue_media on wordpress page

I am using a custom theme that when I access http://ift.tt/1Rsgpca , it gives the error that

upload-media.js?ver=1:3 Uncaught TypeError: Cannot read property 'editor' of undefined

it happends at the code _orig_send_attachment = wp.media.editor.send.attachment;

some google search (like here http://ift.tt/1qbGYGK ) suggests that "Above code snippet works on post edit page only, to make it work elsewhere you need to use wp_enqueue_media(); in your theme. Thanks to daviedR for correcting me on this."

Any idea how to do call wp_enqueue_media() on this page?
