Installation difficulties with php-4.3.1and apache_1.3.27

I'm attempting to install php-4.3.1 and apache_1.3.27 on RedHat 9. After extracting the .tar files to /usr/local/src, I followed the directions from the PHP manual chapter 49, question 9 and performed the following steps with the following results: cd /usr/local/src/php-4.3.1 ./configure --with-apache=/usr/local/src/apache_1.3.27 >checking for Apache 1.x module support... yes - Apache 1.3.x >configure: error: Please run Apache\'s configure or src/Configure >program once and try again cd /usr/local/src/apache_1.3.27 ./configure > no errors cd ../php-4.3.1 ./configure --with-apache=/usr/local/src/apache_1.3.27 > no errors ./make ext/mysql/libmysql/my_lib.o(.text+0x37a): In function `my_dir': /usr/local/src/php-4.3.1/ext/mysql/libmysql/my_lib.c:169: undefined reference to `errno' ext/mysql/libmysql/my_lib.o(.text+0x546): In function `my_stat': /usr/local/src/php-4.3.1/ext/mysql/libmysql/my_lib.c:588: undefined reference to `errno' ext/mysql/libmysql/my_malloc.o(.text+0xbd): In function `my_malloc': /usr/local/src/php-4.3.1/ext/mysql/libmysql/my_malloc.c:24: undefined reference to `errno' ext/mysql/libmysql/my_realloc.o(.text+0xb4): In function `my_realloc': /usr/local/src/php-4.3.1/ext/mysql/libmysql/my_realloc.c:44: undefined reference to `errno' ext/mysql/libmysql/my_delete.o(.text+0x6d): In function `my_delete': /usr/local/src/php-4.3.1/ext/mysql/libmysql/my_delete.c:16: undefined reference to `errno' ext/mysql/libmysql/my_tempnam.o(.text+0x79):/usr/local/src/php-4.3.1/ext/mysql/libmysql/my_tempnam.c:108: more undefined references to `errno' follow collect2: ld returned 1 exit status make: *** [sapi/cli/php] Error 1 Any ideas?
