I checked out the latest code and downloaded all necessary third party softwares and for couple of softwares (like openldap, sleepycat) i renamed the version and created tgz and it then at last i ran the make commond as mentioned in install-cvs.txt, which is "make allclean all" and i am getting the following error

This script is a placeholder for the /usr/bin/javac
master link required by jpackage.org conventions. libgcj's
rmiregistry, rmic and jar tools are now slave symlinks to these
masters, and are managed by the alternatives(8) system.

This change was necessary because the rmiregistry, rmic and jar tools
installed by previous versions of libgcj conflicted with symlinks
installed by jpackage.org JVM packages.
