It can't.  The rehash has to be executed within the context of your 
current shell (it's a builtin) and the only place you have that is the 
command line.  Any process you run (like make, portupgrade) has no 
access to that context.

If you are not wedded to tcsh, then bash would do it for you; other 
shells too, perhaps, but I can't say never having tried them.
