FPDI and CodeIgniter, cannot read PDFs

Code:

$pdf->SetSourceFile(base_url()."businesscard.pdf");

Rather than using base_url(), I would define the real path (i.e. /opt/lampp/...).

Incidentally, I'm trying to integrate FPDI myself. I've got FPDF working like a charm, but I'm running into issues with FPDI. Care to post a quick outline of how you installed FPDI?
