Hello Ingo,
Since you are using `sudo` to install, it is using the root user's
environment (actually a reduced environment that `sudo` creates*) which
does not have `XDG_RUNTIME_DIR` set. Gnuplot needs to have
`XDG_RUNTIME_DIR` set in order to run during the dist's tests. You can
set the variable to a temporary directory:
sudo bash -c 'XDG_RUNTIME_DIR=$(mktemp -d) cpanm --test-only
PDL::Graphics::Simple'
I would recommend installing packages to a `local::lib` instead of using `sudo`.
Best regards,
- Zaki Mughal
