Upgrade to WO 4.0 and make does not work!

[Endre Meckelborg Rognerud <e.m.rognerud@usit.uio.no>]

I've just upgraded from WO 3.51 to WO 4.0. This was not easy, but it works
now. But it took me ca. 1 minute to find an error. I upgraded one of my
projects and tried to compile it. I got the following error:

"C:/Apple/NextDeveloper/Executables/make: not found"

In my folder C:\Apple it is a folder Developer, not NextDeveloper. Ok... I
copy this folder to another one called NextDeveloper. Now it works to
compile, but not without errors. I've heard that it should be a script for
upgrading old projects in WO 4.0, because a lot has changed in the class
hierarchy for Java. I can't see that this works. It fails in
Application.java with the message:

"Package next.util not found in import."

This is the first statement in my project :-) Do I do something wrong, or is
it just really hard to upgrade to WO 4.0?

Interested in comments!!
