I am no expert on Adobe apps, however, I just reloaded my Mac tower with Tiger (only Tiger lets the disk utility see my added DVD burner) so i had a fresh install to work with. I loaded InDesign 2.0 and made a document. I do not have any other Adobe apps on this machine. From the file menu, there is an "Export" option, one of the choices is PDF. I exported the document, and it opened on my PC which only has Acrobat reader installed. Hope that helps.
