Carlo's change to configure.ac works for me.

When I try "dlgtest(0)" I get ...

        Java JDK home directory  does not exist.
        Please adapt java_home in dlgtest.m.

Setting JAVA_HOME to that used during the build gives ...

        setenv JAVA_HOME "/System/Library/Frameworks/JavaVM.framework/Home"

Now "dlgtest(0)" results in ...

        0 ... STOP
        1 ... listdlg tests
        2 ... errordlg tests
        3 ... warndlg tests
        4 ... helpdlg tests
        5 ... inputdlg tests
        6 ... TeX code tests
        Run which test?   [0] > 

Is this the expected result?
