I can't seem to be able to find a way to compile php with oracle and pdflib support.  I am experiencing the following errors:

When running "configure" with the following options:
./configure \
--with-apxs=/usr/sbin/apxs \
--with-sybase \
--with-pdflib \
--with-oracle \
--with-zlib \
--with-gd \
--enable-sigchild \
--without-mysql \
--with-system-regex \
--with-config-file-path=/etc/httpd

configure dies and I recieve the following error message:
configure: error: 
PDFlib extension requires at least pdflib 3.x. You may also need libtiff, libjpeg, libpng and libz.
Use the options --with-tiff-dir=<DIR>, --with-jpeg-dir=<DIR>, --with-png-dir=<DIR> and --with-zlib-dir=<DIR>
See config.log for more information.


config.log has the following message on the last several lines:
configure:51569: checking for PDF_show_boxed in -lpdf
configure:51588: gcc -o conftest -g -O2  -DLINUX=22 -DEAPI -DEAPI_MM -DEAPI_MM_CORE_PATH=/var/run/httpd.mm  -Wl,-rpath,/home/oracle/OraHome1/lib -L/home/oracle/OraHome1/lib conftest.c -lpdf  -lz -lm -ldl -lm -ldl -lgd -lz -lcrypt -lresolv -lm -ldl -lnsl  -lresolv -lcrypt -lclntsh -lclntsh 1>&5

collect2: ld returned 1 exit status
configure: failed program was:
#line 51577 "configure"
#include "confdefs.h"
/* Override any gcc2 internal prototype to avoid an error.  */
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char PDF_show_boxed();

int main() {
PDF_show_boxed()
; return 0; }

I sat around for nearly an hour playing around with various options until I discovered that if I attempt to configure php without the "--with-oracle" option everything works without a problem and I can compile successfully (without oracle support of course).  PDF support works without a problem (I generated a sample pdf document just to be sure).  If put back in the "--with-oracle" option and remove the "--with-pdflib" option once again php compiles successfully (without pdflib support) and Oracle support works correctly.
As always, any suggestions are greatly appriciated.
