[OS X TeX] xdvi under Tiger

[Juergen Fenn]

Hello,

I've just switched from Windows to the Mac, still running Tiger and 
MacTeX from the TeX Collection 2007 DVD. Apple's X11 is installed.

When I try to start xdvi Tiger yields the following:

---------------------------------------------

Welcome to Darwin!
arnoschmidt:~ juergen$ which xdvi
/usr/texbin/xdvi
arnoschmidt:~ juergen$ xdvi
Error: Can't open display:
arnoschmidt:~ juergen$
---------------------------------------------

I'm stuck. :-/ What else do I have to do in order to run xdvi?

Thanks in advance!

Regards,
Jürgen.
