在Fedora上安装gfortran时包版本的冲突

Question

我使用命令yum install gcc-fortran在我的Fedora Linux系统上安装gfortran。但是我收到以下错误：

Error: Package: gcc-gfortran-4.4.6-3.el6.x86_64 (base_install-Server)
           Requires: gcc = 4.4.6-3.el6
           Installed: devtoolset-2-gcc-4.8.2-15.1.el6.x86_64 (@rhel-x86_64-server-dts2-6)
               gcc = 4.8.2-15.1.el6
           Installed: gcc-4.4.7-11.el6.x86_64 (@rhel-x86_64-server-6)
               gcc = 4.4.4-15.el6
               gcc = 4.4.7-11.el6
           Available: gcc-4.4.6-3.el6.x86_64 (base_install-Server)
               gcc = 4.4.6-3.el6
               gcc = 4.4.4-15.el6
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我该如何纠正这个问题？
