无法在Centos7上安装php-mssql或freetds

我的目标是使用PHP连接到MS SQL Server 2005。我已经安装了PHP和ODBC。我正在运行CentOS7。

PHP Version => 5.4.16

....（来自php -i）....

odbc

ODBC Support => enabled

尝试安装freetds和php-mssql扩展时遇到2个依赖问题。（见下文）

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我有libgnutls.so版本28

/usr/lib64/libgnutls.so.28
/usr/lib64/libgnutls.so.28.20.4
