See haru for an open source alternative.
Well, I never really liked PDFlib (Lite). It's bloated with its own copies of tiff, png, jpeg and zip libraries. It's "open source" license isn't all that compatible with other true open source licenses. If you really want PDFlib, here's the basics, and you'll have to figure out the rest on your own.
PDFlib Lite source comes on a handy Mac OS X disk image. Mount the image and option-drag the disk to where you build your source. In a Terminal type (supply admin password when asked):
./configure --disable-dependency-tracking \ --without-java --without-tcl --without-perl --without-py --without-ruby \ --enable-large_files --disable-cxx --enable-tiffwrite CFLAGS=-Os make sudo make install
