I'm having a similar problem. Originally, pdflib wasn't making the libraries as it said it was (or so it seemed) so I compiled and installed the latest libtiff and jpeg I could find, and tried again. This time I got the pdflib libraries to install, but when I go and try compiling PHP I get errors. It claims that I need pdflib 3.x. I've installed 3.02, so that's not the problem. It also said (if I don't specify the dir) that I may need libtiff and jpg as well, when I supply PHP with the dirs to these libs, it fails to find them, and still fails. Any suggestions?
