PHP & Apache

[ksbrace]

Hello,
I'm in the process of setting up Apache, PHP on Redhat using Oracle. I was attempting to follow along an install tutorial from Oracle's Tech pages:

http://www.oracle.com/technology/tech/opensource/php/apache/inst_php_apache_linux.html

I have Apache set up properly and Oracle Application Server also up and running. I ran the .configure file w/no problems:

./configure --with-oci8=$ORACLE_HOME \
          --with-apxs=/oracle/app1/oracle/product/1.0.2/Apache/Apache/bin/apxs \
          --enable-sigchild

But, when I run make, I get the following error:

oracleas@ias:/oracle/php-4.3.9 > make
/bin/sh /oracle/php-4.3.9/libtool --silent --preserve-dup-deps --mode=compile gcc -DSOLARIS2=260 -DMOD_SSL=206104 -DMOD_PERL -DUSE_PERL_SSI -DEAPI -DUSE_EXPAT -I/oracle/app1/oracle/product/1.0.2/Apache/Apache/include -Isapi/apache/ -I/oracle/php-4.3.9/sapi/apache/ -DPHP_ATOM_INC -I/oracle/php-4.3.9/include -I/oracle/php-4.3.9/main -I/oracle/php-4.3.9 -I/oracle/php-4.3.9/Zend -I/oracle/app1/oracle/product/1.0.2/rdbms/public -I/oracle/app1/oracle/product/1.0.2/rdbms/demo -I/oracle/php-4.3.9/ext/xml/expat -I/oracle/php-4.3.9/TSRM -g -O2 -prefer-pic -c /oracle/php-4.3.9/sapi/apache/sapi_apache.c -o sapi/apache/sapi_apache.lo

I googled the error, but came across several conflicting solutions that weren't useful. Any help would be greatly appreciated. Thanks in advance!!!
