An error like that usually means you are trying to open a graphical
application remotely or as a different user and you don't have permission to
open the display.  In this case your display is :0.0.

On my system the display is :0
$ env|grep DISPLAY
DISPLAY=:0

Can it be safely removed, and re-installed, or is there, (hopefully),

What were you doing when the message occurred?

If it is just an error message and it isn't causing any real problems just
ignore it.

If you were trying to open synaptic remotely with ssh try adding ssh -X
hostname.  Or better yet use apt-get or aptitude to update the machine.

No!

And why did you need to rebuild it in the first place?
