Yes that is why I do a require first and only when that fails I do the install.

So when I have the module the require succeeds and I do not run the install.

    And how do you check if the already installed module has the correct version? :)

    sudo cpan -D List::Util CPAN: Storable loaded ok (v2.21) Going to read '/home/lanx/.cpan/Metadata' Database was generated on Wed, 18 Dec 2013 18:41:02 GMT List::Util ---------------------------------------------------------------------- +--- List utilities (eg min, max, reduce) P/PE/PEVANS/Scalar-List-Utils-1.35.tar.gz /usr/local/lib/perl/5.10.0/List/ Installed: 1.22 CPAN: 1.35 Not up to date Graham Barr (GBARR)

      Well this is really just a hack and for the time being I don't care about version.

      Detecting that a module is installed is good enough.

      I grant you that it is not the cleanest, but my problem is that I want to automate the installation of some third-party software that does not explicitely lists dependencies on particular versions.

      I can't do any better at the moment.

    Should cpanminus be part of the standard Perl release?
