Century gothic font problem with pages 09

I have a document using century gothic with Pages 09 on an Intel Mac with the most recent Snow Leopard upgrade. It looks and prints fine. When I transfer this document to another computer with pages 09 the century gothic font is missing and pages asks if I want to replace with another font. What can I do? I need century gothic. This second computer is a G4 so it has the most recent version of Leopard. I need to use this G4 to print large quantities.

I have all of the fonts loaded onto this computer using the Leopard extras installer DVD. Century gothic is not one of the included fonts. Does anyone have any suggestions? I have Century Gothic on the Intel mac probably because of numerous Adobe products on the Intel Mac. If I load say Photoshop on the G4 mac then maybe Pages will recognize Century gothic once this font is loaded onto the G4. I converted the document to a PDF and then tried to print from the G4. It almost worked but the last line in the document get it's lower half chopped off. Any suggestion?
