I originally downloaded and unzipped gwt-mac-1.6.4 and only later
found out that GWT Designer can't work with it, and so I downloaded
and unzipped gwt-mac-1.5.3. As far as the GWT Eclipse plugin, that's
an entity unto itself and I don't know what GWT it installed within
the bowels of Eclipse. In the preferences, I set the GWT home (I'm
presuming that preference is for the plugin) to the gwt-mac-1.5.3
directory. I have at no time intentionally downloaded a linux version
unless, of course, it was bundled with something and I was unaware of
it.
Can you give me the name of a specific file that might be in the Linux
distro and I can do a find to see if I can find it.
