Well it didn't work.

I used "setenv FTP_PASSIVE_MODE no" and retried "make all " 
in /usr/ports/samba but I only got "Internal Server Error".

Then I tried with FTP_PASSIVE_MODE=yes and got the same error.

At some point I logged out and then back in and retried with my 
unchanged environment.  To my surprise I received a "Login:" prompt 
after the third "Internal Server Error" (This was the third source host 
in the Makefile list).  I entered "anonymous" because I assumed it was 
the remote server and NOT my proxy server.  Then I was prompted 
with "password:" so I entered that.  Then I got "Internal Server Error" 
and I have not been able to reproduce that.

How frustrating.
