title: How can I install the perl-RRD-Simple package on CentOS 7?
body: <p>I'm trying to install <a href="http://tsung.erlang-projects.org/" rel="nofollow noreferrer">TSung</a> on CentOS 7, but I'm having trouble installing the dependencies.</p>
  
  <p>When I tried to install perl-RRD-Simple.noarch, yum shows no package available. So I downloaded an RPM file and did:</p>
  
  <pre class="lang-none prettyprint-override"><code>rpm -ivh perl-RRD-Simple-1.43-1.el5.rf.noarch.rpm
  </code></pre>
  
  <p>But I got an error:</p>
  
  <pre class="lang-none prettyprint-override"><code>error: Failed dependencies:
          perl(RRDs) is needed by perl-RRD-Simple-1.43-1.el5.rf.noarch
  </code></pre>
  
  <p>How can I install the perl-RRD-Simple package? RRDtool is already installed.</p>
