This suggestion was very helpful. The problem using the JDK 5 on the Mac is
that instead of having an rt.jar they have classes.jar and ui.jar so you
can't use the --with-openjdk-home  so you must use
--with-libgcj-jar=/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Classes/classes.jar
but unfortunately I had a typo in the path. I have been reading your posts
but much is new and I certainly don't understand it all.

Removing the --with-libgcj-jar cuts off the path to what I am attempting to
do. (icedtea6 no longer works since I updated) If you can use any java 5
complier to create IcedTea JDK, the resultant can be used after that. If it
is possible to keep IcedTea like IcePick "which allows the OpenJDK language
tools (javac, javadoc, javah, javap, apt) to be built separately using any
1.5 compliant Java compiler..." that would be great. Unless there is an
alternate way to point to the runtime jar.

I built gcc 4.2 as this was available via MacPorts.

 Icedtea still looks promising but now I'm stuck on the ALSA part of
configure.

checking for ALSA... no
configure: error: Could not find alsa -   Try installing alsa-lib-devel.

The only thing I could find remotely related was Libao2.

Note: the problem I had before fwas because I was missing pkg.m4 which in
turn got fixed when I installed xorg-libX11.

./configure: line 11562: syntax error near unexpected token `XPROTO,'
./configure: line 11562: `PKG_CHECK_MODULES(XPROTO,
xproto,XPROTO_FOUND=yes,XPROTO_FOUND=no)
