Dear all, I am hitting a wall trying to install the latest Demeter version on my ubuntu laptop. System: Ubuntu 14.04 Demeter: 0.9.26 perl: 5.18.2 pdl and pdl::stats from repositories. (I tried a newer versions from cpan, but ot no avail) moose: initially from repositories, than vs. 2.2011 from cpan I did follow the installation instructions on https://bruceravel.github.io/demeter/documents/SinglePage/demeter_nonroot.ht... and tried to install demeter in ~/perl5 and also the instructions in: https://bruceravel.github.io/demeter/documents/SinglePage/installation.html to install Demeter as sudo Both attempts ended with the same result when I start dathena in a terminal the image of the goddess appears briefly and I get the following error messages in the terminal: --------------------------------------------------------------------- Invalid version format (non-numeric data) at /usr/local/lib/perl/5.18.2/Moose/Exporter.pm line 11, <DATA> line 90.

Any hint would be welcome, upgrading ubuntu to a newer LTS version might be useful (It is absolutely possible that something is weird with this installation after a lot of playing around) but I am currently reluctant to do so, because it will for sure break other things...
