Comment (by cmbarton):

 My only change so far has been to the code for Mac. On that platform, you
 have something called xterm (and it can be a couple of different things)
 or you don't. Good point that there needs to be error trapping for the
 times when you don't. This is easy to add. ISTR that the xterm wrapper for
 Mac was a port from the Linux xterm wrapper Linux. It has always been iffy
 for working on the Mac, even in TclTk. The terminal won't substitute for
 an xterm in the commands that require one, primarily because of need for
 graphics. The terminal can open an xterm at need, but only if xterm
 exists. Also, this doesn't always work right for the old commands that
 expect one. Hence the need to guarantee one--and as you note, gracefully
 trap the situations where Mac owners have not installed xterm.

 I left all the linux stuff alone because I'm not sure what the context for
 the wrapper is. But it might be better if there is an environmental
 variable GRASS_XTERM that is set to a platform specific value than a
 script that tries to figure it out. On the other hand, this may not be
 worth the trouble for the remaining life of version 6.
