since it was created.

had you actually *read* my message, you would have seen the phrase "fully
updated"  in my description of what version of RH i am using.  i am using
these exact packages.  better luck next time; your stab-in-the dark may
hit something...

in the meantime, i've figured out a little more.  if i 'strace mail' and
then try to delete my messages, i see that mail(1) is trying to create a
lockfile in /var/spool/mail (called something like
/var/spool/mail/.man.dynatec.com.63f8d).  of course it fails, since users
don't have permission to write stuff like that into /var/spool/mail.

question:  is there an environment variable that can re-direct mail(1) to
write its lock files someplace else?  the man page doesn't seem to
indicate so, but that doesn't necessarily mean anything.

informal poll:  does anybody use mail(1)?
