It actually wants to see com.sun.javac (or whatever
the class for Sun's javac compiler is), as far as I
know. Of course, you won't find it in kaffe's
tools.jar ,)

You could either put Sun's tools.jar from JDK1.X , X
>= 2 into your classpath, or set the property
build.compiler to kjc or jikes in the buld.xml file.

If you want to help to fix that bug, please report
bugs in gcj to the gcj mailing list or bug tracking
page ;) Gcj runs natively and doesn't use kaffe, as
far as I know. There are rpm packages of jakarta
packages compiled to binary using gcj somewhere , I
read about it here:
