. Make this port run. Its always built correctly, but I've had problems
running it. The changes include:
. Pull in stubs for the MRJToolkit classes. These are not used, but
some are imported, so the app was failing with NoClassDef errors.
. Eliminate the build dependency on Perl.
. Use standard ways of depending on Java.
. Don't install unnecessary stuff.
. Install in appropriate directories and respect NOPORTDOCS.
. Replace the relatively complicated and non-working launcher script
supplied with a simple version that uses javavm(1).
