This is a problem with window creation. I presume it's occurring because 
you aren't running the program in a windowed environment - if you've 
logged in through a graphical screen such as xdm and you are running the 
program in a window on a desktop the DISPLAY environment variable is 
normally set up for you.

Perhaps you are just telnetting in from a remote system?
