I'd say it's a missing environment variable setting.
If you've got a bourne or bash shell, try:
export DISPLAY :0.0
This assumes you're sitting at the console of the machine
you're trying to build/run on.
If you're ssh'ed into a machine, then you'd need to set the
DISPLAY variable to the hostname or IP of your machine with
the X11 graphics console, and be sure that console allows
remote X11 connections (xhost +, TCP is not disabled by firewalls
or by the graphics console's X11 config, etc..)

'Can't open display' almost always means no other GUIs should work
either,
and most likely the problem is either you don't have the DISPLAY
environment
variable set properly.
As Matt asks; see if any other GUIs open from the command line.
I would assume things like 'xmag', 'xterm', 'firefox', and other
such default X11 programs would yield the same error.
