CentOS附带libxml2-2.6.26.我必须安装至少2.7.X版本.
我从XMLSOFT(http://xmlsoft.org/sources/)下载了libxml2,libxml2-devel和libxml2-python(2.7.8)的RPM.
我试图以这种方式安装它：
# yum localinstall libxml2-2.7.8-1.x86_64.rpm libxml2-devel-2.7.8-1.x86_64.rpm libxml2-python-2.7.8-1.x86_64.rpm
我得到：
Examining libxml2-devel-2.7.8-1.x86_64.rpm: libxml2-devel-2.7.8-1.x86_64
Marking libxml2-devel-2.7.8-1.x86_64.rpm as an update to libxml2-devel-2.6.26-2.1.2.8.el5_5.1.x86_64
Examining libxml2-python-2.7.8-1.x86_64.rpm: libxml2-python-2.7.8-1.x86_64
Marking libxml2-python-2.7.8-1.x86_64.rpm as an update to libxml2-python-2.6.26-2.1.2.8.el5_5.1.x86_64

You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.
更新glibc是否安全？或者从源代码安装libxml2？
确保安装了开发工具：
yum groupinstall "Development Tools"
抓住src rpm：
wget http://xmlsoft.org/sources/libxml2-2.7.8-1.src.rpm
由于rpm版本不同,你将无法直接调用rpmbuild,所以让我们短路：
rpm -ivh libxml2-2.7.8-1.src.rpm --nomd5
然后：
rpmbuild -ba /usr/src/redhat/SPECS/libxml2.spec
此时可能会提示您输入某些依赖项(如果是这样,只需安装相关的依赖项,然后重新运行上面的rpmbuild -ba命令).
假设你的构建成功完成(我刚刚在这里的CentOS 5盒子上进行了测试,它构建得很好),得到的RPM将在：
/usr/src/redhat/RPMS/arch
其中“arch”是x86_64或i386,具体取决于您的系统.你可以从那里yum localinstall –nogpgcheck包.
