Dear all, I am trying to install demeter on my debian 7 computer and I cannot reach the end of the compilation. I followed the instructions from the https://gist.github.com/3959252 page. First, the "perl ./Build.PL" still requires "PDL::stats" even after several "./Build installdeps". I have the following message: """""""""""""""""""""""""""""""""""""""""""""""""""" letard@pcikieffer:~/demeter$ perl ./Build.PL Checking prerequisites... requires: ! PDL::Stats is not installed ERRORS/WARNINGS FOUND IN PREREQUISITES. You may wish to install the versions of the modules indicated above before proceeding with this installation Run 'Build installdeps' to install missing prerequisites. Created MYMETA.yml and MYMETA.json Creating new 'Build' script for 'Demeter' version 'v0.9.21' If all dependencies are met, build and install Demeter by doing: ./Build ./Build test ./Build install # (or sudo ./Build install) If you are reinstalling Demeter after updating your operating system (or updating perl), you may find that none of the programs will run successfully. You may need to do: ./Build touch_wrapper ./Build test ./Build install # (or sudo ./Build install) """""""""""""""""""""""""""""""""""""""""""""""""""" Then, I decided to continue despite this missing prerequisite and the "./Build" ends with the folowing error: ##### Building Artemis User's Guide Building Athena User's Guide ! plugin error - Can't locate Clone.pm in @INC (@INC contains: /home/letard/perl5/lib/perl5/x86_64-linux-gnu-thread-multi /home/letard/perl5/lib/perl5/x86_64-linux-gnu-thread-multi /home/letard/perl5/lib/perl5 /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl .) at /usr/local/share/perl/5.14.2/PPI/Element.pm line 25.

If one of you has some ideas to help me going further, I would really appreciate! Thanks a lot in advance.
