如果有人可以帮助我，我真的很感激。我正在尝试安装PHP 5.5.8，我的configure语句如下：
./configure --prefix=/usr/local/php
--with-apxs2=/usr/local/apache2/bin/apxs
--with-libdir=lib64
--with-tidy=/usr
--with-gd
--with-png-dir=/usr/local
--with-zlib-dir=/usr/local
--with-mysqli
--with-mysql
--with-xsl
--with-curl
--with-jpeg-dir=/usr/local
--enable-soap
--with-libxml-dir=/usr/local
--enable-mbstring
--with-ldap
--with-pear
并且输出“make”时出现一串错误，如：
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libexslt.so: undefined reference to `xmlNewChild@LIBXML2_2.4.30'
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libxslt.so: undefined reference to `xmlParserGetDirectory@LIBXML2_2.4.30'
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libxslt.so: undefined reference to `xmlDictQLookup@LIBXML2_2.6.0'
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libxslt.so: undefined reference to `xmlNewText@LIBXML2_2.4.30'

/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libexslt.so: undefined reference to `xmlXPathPopBoolean@LIBXML2_2.4.30'
collect2: ld returned 1 exit status
make: *** [sapi/cli/php] Error 1
我有三台RHEL 6服务器，所有服务器都有相同版本的PHP和Apache（2.4.7），并且安装在两台服务器上运行正常，但在第三台服务器上运行不正常，只有在省略“--with-xsl”时安装才有效“。有没有人对我在这里失踪的想法有什么看法？我真的需要让这个工作，到目前为止我没有尝试过任何改变。
