Hey Mike -

Good to hear from you. Thanks for the offer to help. Tell Francois and  
the guys I said hey.

So, there are recently updated instructions for building OpenJDK 7 on  
10.5 on a wiki page. See:

	http://wikis.sun.com/display/OpenJDK/Darwin9Build

If you go to the BSDPort wiki page, there is a link (external to the  
wiki) to instructions for building this on Snow Leopard. I have not  
done the build on 10.6, so I cannot speak to it. But nobody has  
complained on the mailing list.

	http://wikis.sun.com/display/OpenJDK/BSDPort

I noticed that, in my installed build products, the OpenJDK bin  
directory does not contain everything, for example, that is in /System/ 
Library/Frameworks/JavaVM.framework/Versions/1.6.0/Commands, so there  
will be some mis-matches to deal with.

If you want to see what is produced by the build of OpenJDK 7 on 10.5  
at this time, I did a "find -ls" in the products directory and that is  
at http://www.wykiwyk.com/openjdk/openjdk7_ToC.txt.

cheers - ray
