The existing java package has a couple of issues on Mac OS X:

1)  It sets JAVA_INCS improperly for current OS X Java, so it doesn't
build out of the box. Using

JAVA_INCS="-I/System/Library/Frameworks/JavaVM.framework/Versions/A/Headers"

works on 10.5, 10.6, and 10.7.

2)  Items like msgbox() which are supposed to open up a window don't
seem to work:

octave-3.4.3:4> msgbox("foo")
