+      
+      <para>CentOS 7.5 has a very old gcc compiler 4.8.5.  Some sysrepo
+      dependencies require at least 4.9, which unfortunately means that
+      a new compiler has to be installed. Also, many of the Sysrepo dependencies
+      are not avalable in CentOS as packages, so for the time being they
+      need to be installed from sources. The situation is expected
+      to improve over time as more and more CentOS/RedHat packages
+      become available.</para>
