Sorry I never got back to you on this one.  Sheesh, have I ever been busy
since you posed it three weeks ago.  Anyway, the simple answer is: "puts
$errorInfo".  See "man n error" for more info.

We could probably improve the Tcl error handling (not to mention many other
areas of Tcl support) in plplot.  I didn't get to do as much with this over
the last year as I wanted but am still hoping..
