Jeff,
Thanks for all your help and suggestions. Renaming the directory
worked fine and Eclipse came right up and I also removed the gwt-
mac-1.6.4 directory. The amples that come with gwt-mac-1.5.3 don't
include a build.xml file for ant. Instead you run the included shell
script. Still had the same problem. Here's the stack trace again and
my first clue:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-pi-
gtk-3062 in
java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1753)
at java.lang.Runtime.loadLibrary0(Runtime.java:822)

100)

at com.google.gwt.dev.GWTShell.<clinit>(GWTShell.java:301)
Where did those org.eclipse.swt.... calls come from. Eclipse was
totally out of the picture. I unset the CLASSPATH and that didn't
solve it. Finally found the culprit. In lib/ext there were two swt
jarfiles, and they were gtk (meaning they were for linux). Why and
when they got there is a mystery. I removed them and it now all
works. The Instantiations GWT Designer is still having a problem not
being able to instantiate a widget class. I'm going to trash the
tutorial application and rebuild it. Now that all the conflicting
pieces are out, it will probably work as advertised this time.
Thanks,
Rob
