res_search & dn_expand undefined reference php 4.2.1 / apache 1.3.26 / redhat 6.2

Hey everyone, I'm getting this error regarding the PHP source files when compiling Apache. These are the arguments I used to configure php 4.2.1: ./configure --with-apache=../apache_1.3.26 \ --with-jpeg-dir=/usr/local/lib --with-pgsql --with-gd \ --with-ttf=/usr/local/lib --with-t1lib=/usr/local/lib \ --enable-gd-imgstrttf \ --enable-trans-sid --with-imlib=/usr/lib --with-mysql and this is what I used to configure apache 1.3.26 : ./configure \ "--with-layout=Apache" \ "--prefix=/usr/local/apache" \ "--activate-module=src/modules/php4/libphp4.a" \ "--enable-module=so" \ "$@" [...snip] <=== src/modules gcc -c -I./os/unix -I./include -DLINUX=22 -I/usr/local/src/php-4.2.1 -I/usr/local/src/php-4.2.1/m ain -I/usr/local/src/php-4.2 .1/main -I/usr/local/src/php-4.2.1/Zend -I/usr/local/src/php-4.2.1/Zend -I/usr/local/src/php-4.2.1/T SRM -I/usr/local/src/php-4.2 .1/TSRM -I/usr/local/src/php-4.2.1 -DUSE_EXPAT -I./lib/expat-lite ./apaci modules.c gcc -c -I./os/unix -I./include -DLINUX=22 -I/usr/local/src/php-4.2.1 -I/usr/local/src/php-4.2.1/m ain -I/usr/local/src/php-4.2 .1/main -I/usr/local/src/php-4.2.1/Zend -I/usr/local/src/php-4.2.1/Zend -I/usr/local/src/php-4.2.1/T SRM -I/usr/local/src/php-4.2 .1/TSRM -I/usr/local/src/php-4.2.1 -DUSE_EXPAT -I./lib/expat-lite ./apaci buildmark.c gcc -DLINUX=22 -I/usr/local/src/php-4.2.1 -I/usr/local/src/php-4.2.1/main -I/usr/local/src/php-4.2. 1/main -I/usr/local/src/php- 4.2.1/Zend -I/usr/local/src/php-4.2.1/Zend -I/usr/local/src/php-4.2.1/TSRM -I/usr/local/src/php-4.2. 1/TSRM -I/usr/local/src/php- 4.2.1 -DUSE_EXPAT -I./lib/expat-lite ./apaci -rdynamic \ -o httpd buildmark.o modules.o modules/standard/libstandard.a modules/php4/libphp4.a main/libmain.a ./os/unix/libos.a ap/l ibap.a lib/expat-lite/libexpat.a -Wl,-rpath,/usr/local/lib -Wl,-rpath,/usr/local/pgsql/lib -rdynamic -L/u sr/local/lib -L/usr/ local/pgsql/lib -Lmodules/php4 -L../modules/php4 -L../../modules/php4 -lmodphp4 -lpam -lpq -lgd -l t1 -lttf -ljpeg -lcrypt -lre solv -lm -ldl -lnsl -lresolv -lcrypt -lm -lcrypt -ldl modules/php4/libphp4.a(dns.o): In function `zif_checkdnsrr': /usr/local/src/php-4.2.1/ext/standard/dns.c:246: undefined reference to `__res_search' modules/php4/libphp4.a(dns.o): In function `zif_getmxrr': /usr/local/src/php-4.2.1/ext/standard/dns.c:307: undefined reference to `__res_search' /usr/local/src/php-4.2.1/ext/standard/dns.c:334: undefined reference to `__dn_expand' collect2: ld returned 1 exit status make[2]: *** [target_static] Error 1 make[2]: Leaving directory `/usr/local/src/apache_1.3.26/src' make[1]: *** [build-std] Error 2 make[1]: Leaving directory `/usr/local/src/apache_1.3.26' make: *** [build] Error 2 [...snip] and the compile then dies. I've searched the groups and there are some references to this problem, but no solutions that I can find. Redhat 6.2 is the OS. Thanks Dan
