When installing a test of 7.0 B4, I found that directories which I have 
traditionally used
(/usr/local/libexec  /usr/local/include  /usr/local/lib  
/usr/local/sbin  /usr/local/man/*  etc)
and /etc/make.conf are not visible in a default install. Is this because 
the B4 is missing them, or has there
been a serious change in directory & file structure?
