 One of those infuriating habits of oldtimers is still using a million year
 old .cshrc file even though running tcsh -- which still honors the .cshrc
 file. Previous versions of macports wrote to my .cshrc, but this new rc1
 creates a .tcshrc where one was not present, overriding the existing
 .cshrc (rendering it temporarily moot and creating much surprise!)

 Obviously easily cured, but testing for the presence of .cshrc would be a
 nice touch.
