I realize that I forgot to attach the list of packages emerge wants to
reinstall.  So I did the same emerge command (I always use --ask) and
they are *gone*.  This I don't understand since I didn't sync inbetween
(ls -lt /usr/portage shows nothing since wednesday).

I though all dependencies, etc are resolved locally so why would it
change from 44 packages with 38 reinstalls to 4 packages with no
reinstalls?

Could someone please set me straight?

thanks,
