Hi Ed, I see what you mean. But then it is just me having access to those modules and not other users. Are you suggesting it is best practice to install perl modules per user? That requires a lot of redundant work if you have a group using the software.
I suppose in the particular case, catching an empty XDG_RUNTIME_DIR and setting to some temp directory would resolve the issue.
