[Vala] Can't compile some code example...

[Arkadi Viner <arkashkin gmail com>]

Hi,
I'm want to use the poppler library to display some pdf document,
I have found this example on the internet:
http://code.valaide.org/content/poppler-sample
But it doesn't compiles with the newest vala (0.9.1), maybe some one knows
what should be done to make it compile?

*It shows me all this errors:*
