There are some bigger issues than just getting it to build... poppler 
doesn't like poppler-qt3
 From the Arch poppler PKGBUILD

package_poppler() {
   pkgdesc="PDF rendering library based on xpdf 3.0"
   depends=('libjpeg' 'gcc-libs' 'cairo' 'libxml2' 'fontconfig' 
'openjpeg' 'lcms' 'poppler-data')
   conflicts=("poppler-qt3<${pkgver}")

   cd "${srcdir}/${pkgbase}-${pkgver}"
   make DESTDIR="${pkgdir}" install

   rm -f "${pkgdir}"/usr/lib/pkgconfig/poppler-{glib,qt4}.pc
}

In order to get rid of poppler,  qt3 will need to be built without cups 
support as cups drags in poppler.  Then one has the problem of building 
kde3/trinity with cups support again dragging in poppler.

What I am doing is building kdegraphics without -DWITH_PDF=ON, kpdf 
works without poppler-qt3.

I am also trying to take poppler from arch and build the qt4 and the qt3 
bindings,  hopefully I will be successfull.
