Now that most of this section has been bludgeoned into relative 
submission, returning to this issue mentioned by Benjamin Kaduk in -doc:

quote from the proposed new version:
   The value of PREFIX will be set to LOCALBASE (defaulting to
   /usr/local).  If USE_LINUX_PREFIX is set, PREFIX will be LINUXBASE
   (defaulting to /compat/linux).

Quoth Benjamin Kaduk:

> I don't think we've yet said something like: LOCALBASE should be set 
> to where existing ports have already been installed (the ``base 
> directory'' of where the ``local additions'' to the system have been 
> made); it is uncommon for having PREFIX != LOCALBASE in normal usage. 
> We probably should say something like that.

Thinking about this a bit, it seems like something to tell the end user 
rather than the porter.  Although maybe it is something the porter 
should consider.  I don't know.
