I don't know what's available on FreeBSD.  We've tended to use gcj to get
off the starting blocks, but OpenJDK6 works too.

Ok I didn't see that.  Sorry.
As I say, you may still find hg useful for contributing back.

This looks right (from memory anyway).

Can you provide a log of what happens when you run make?  Something
is clearly going wrong, but I can't see what if the tarballs are ok.
Are you starting from a clean directory?
