When I tried to compile PHP4.0RC1 I got the following failure. I would prefer to stay with PHP3.0, but I can't find a copy of pdflib2.01 or 2.0 ANYWHERE... Is there ANY possiblity of support for libpdf3.0 with PHP3.0.x?... If not, does anyone know how to solve this compile problem?... 

Thanks in advance..
