Which one should Pkg.dir() return? How will Julia know about the other one? I know now about Base.LOAD_PATH and Base.LOAD_CACHE_PATH, and know that each of them can have multiple paths in them. Their contents does not seem to have any effect at all on Pkg.dir(), though. Is it possible to have some packages in a system wide global directory, say /usr/local/share/julia/site/... and some user installed packages in a user directory, say ~/.julia/...? How would such setup be achieved?

Thanks for your help!

Would you be able to provide some pointers to documents that describe what the correct setup should be? When I was trying to find that information on the web I got what seemed to me like conflicting pieces of information.

The place where julia expects a package repository can be configured. In your case the setup was incorrect.
