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：

 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？
