If you're using sudo, it's entirely possible that the "root" shell you create did not actually inherit your environment. This depends on how your particular system is set up, I think.

In any case, we don't recommend installing using sudo (or, for that matter, logging in as the root user). This is not just for Amber. Any package using "home-brewed" install scripts could, through malice or (much more commonly) mistakes, make harmful changes to important parts of your system if you do that.

Instead, we recommend that you create an Amber installation directory that you, as the user, own, and perform the installation in there. You then won't need to run sudo and this environment problem should go away.
