note 31976 rejected from function.imagerotate by spic

hi, i use php 4.3.1 with gdlib 2.0.12 statically compiled, png and jpeg works fine, no problems at all, but as i tried to call the imagerotate function, it tells me an error: Fatal error: Call to undefined function: imagerotate() in ..... i dont use the implemented gdlib , it has a lot of problems, other syntax maybe , and dont support truetype1 together with truetype2....:( hmpf any suggestions why this happens? what do i need for it? imagerotate()? thanks in advance, volker
