title: How to find (Debian/Ubuntu/...) packages that provide required Perl modules
body: <p>I found that installing native Debian or Ubuntu Perl packages, such is often more reliable and convenient than "manually" installing Perl modules via <code>cpanm</code> (especially for XS-Modules). Is there an easy way to find these modules given a list of required Perl modules? The most convenient way would be to map a <a href="https://metacpan.org/pod/cpanfile" rel="nofollow">cpanfile</a>, such as</p>
  
  <pre><code>requires 'XML::LibXSLT', '1.78';
  </code></pre>
  
  <p>to a list of distributions and packages that provide the modules for different target platforms:</p>
  
  <pre><code>XML::LibXSLT, Ubuntu 13.04, libxml-libxslt-perl, 1.78
  XML::LibXSLT, Ubuntu 13.10, libxml-libxslt-perl, 1.78
  XML::LibXSLT, Ubuntu 14.04, libxml-libxslt-perl, 1.84
  XML::LibXSLT, Debian squeeze, libxml-libxslt-perl, 1.70
  XML::LibXSLT, Debian wheezy, libxml-libxslt-perl, 1.77
  XML::LibXSLT, Debian jessie, libxml-libxslt-perl, 1.92
  XML::LibXSLT, Debian sid, libxml-libxslt-perl, 1.92
  </code></pre>
  
  <p>P.S.: I guess the information can somehow be looked up from the package repositories of each distribution, e.g. <a href="http://packages.ubuntu.com/" rel="nofollow">http://packages.ubuntu.com/</a> and <a href="https://packages.debian.org" rel="nofollow">https://packages.debian.org</a> but is there a scriptable solution that already does this lookup?</p>
