Two items I am currently investigating:

First, the port complains that it couldn't find /bin/zip.  No wonder, as 
it's /usr/local/bin/zip.  The quickest fix I wanted to try was a 
softlink, so I did that, if it needs it, the *right* fix could come later.

Second, I cd'ed into work/control/make (might be there was an extra 
component in there, I forget) and found out about WITH_LINUX_BOOTSTRAP, 
which I had not seen before.  I am using the Sun Linux jdk14 as a 
bootstrap, so this seems like a likely thing, I set it, and then 
restarted my build.  I don't figure to get any good info from this for 
some hours,
