安装php出现的错误

我是这样编辑
./configure --prefix=/usr/local/php --with-mysql=/usr/share/mysql --with-apxs2=/usr/local/apache/bin/apxs --with-gd=/usr/local/gd --with-freetype-dir=/usr/local/freetype --with-jpeg-dir=/usr/local/jpeg --with-png-dir=/usr/local/libpng --with-mcrypt=/usr/local/libmcrypt
其它所需的GD库都装了，
结果出现
libc.so.6(GLIBC_2.4) is needed by libxml2-2.6.26-2.1.2.i386
rtld(GNU_HASH) is needed by libxml2-2.6.26-2.1.2.i386
有人明白libc.so.6(GLIBC_2.4) 和rtld(GNU_HASH) 这两个包的吗？
在网上搜了下libc.so.6包，说是全称是glibc-2.9-3.i386.rpm，那就下吧，安装以后出现

error: Failed dependencies:
glibc-common = 2.9-3 is needed by glibc-2.9-3.i386
glibc > 2.3.4 conflicts with glibc-common-2.3.4-2.41.el4_7.1.i386
头痛死了，帮忙给解决一下吧，高手们！
