Brakujace biblioteki... ale jakie ?

[pszemaz WP]

Witaj pld-users-pl!

Mam taki malutki skrypcik do zrobienia/skompilowania.
Na programowaniu ogolnie za bardzo sie nie znam, ale od razu mowie ze
wertowalem google i doinstalowywalem paczki jakie tam spotkalem w
opisach/podpowiedziach gdy cytowalem moje "errory" no ale nie pomoglo.

Oto skrypt, w nim w komentarzu na poczatku jest takze linia jaka mam
wywolac:
