Well, you've logged into an X session (Gnome) as some user...but you are
running the installer from the terminal as "root".  So the installer tries
to connect to root's X session to show you a GUI, but there isn't an X
session for root.

Type "exit" to become yourself again (perhaps confirm with the command
"whoami" that you aren't still root).  Now you need to run those export
commands again (you set environment variables for root, not for yourself).
Then type:

sudo ./JAlbuminstall.bin

That runs the installer as you, but with superuser rights.
