It seems you've built emacs without PNG support, or ghostscript is not
on your PATH.  Therefore, doc-view falls back to show you the plain text
contents of the PDF, and then it fails because
`doc-view-pdftotext-program' is also not oun your PATH.

The reason for not showing the PDF as images should be messaged, so
check your *Messages* buffer.

Bye,
