 They used to live in the same directory, and the old code worked.  I
 veto changing PATH, since this is a user-controlled variable that we
 should avoid changing if at all possible.  Please find some other way
 to solve this problem, especially given that the directory
 reorganization initiative has broken this. 
O.K.  I'm pulling mmencode out and we'll require metamail to be
installed separately.
