    <p>Hi Mahmood</p>
    <p>The use of cpanm (which should be easier than cpan) may help
      here.</p>
    <p>In addition, one of the reasons why things get installed manually
      is to allow for the fact that it is easier to download BioPerl at
      the version the Ensembl API is compatible with than install via
      cpanm, as it usually is quite a long process and frequently throws
      up errors. Bio::Root::Version isĀ  part of BioPerl 1.6 and so I
      suspect these errors stem from the BioPerl not being downloaded or
      the PERL5LIB not being correct, which is causing the attempt to
      re-download and install BioPerl giving the huge number of errors
      you are experiencing, <br>
    </p>
    <p>Regards</p>
    <p>Rishi<br>
