As it says in #3 there, you must have have a DGL server (in the sense that you 
have an X server locally) to do that.  This is not something I've ever tried 
to do (I had SGI's on my desk some years back), but unless you can find a DGL 
server for Linux, you'll never make it work.

Options:
1. Try to find a DGL server for Linux.
2. Get a small IRIX machine to sit on your desk to run that app. (and the 
flight simulator :-)
3. Change apps, say to "xosview", which should run on IRIX too and does use 
the X protocol.

HTH,
