Thanks, for letting me know I am not nuts. Unfortunately, I've
already replaced the wrong one with the right one. I guess I need to
get the perl version from somewhere so I can rename it. Do you know
which package contains that version? Thanks.

I'm not exactly sure this is what happened but I can't think of
anything else. After installing several packages from CPAN, my
daily log maintenance began failing. After some investigation I
found that '/etc/periodic/daily/500.daily' was getting an error
from the '/usr/bin/head' command. When I ran 'head' manually the
command was not the normal one. It appears that one of the perl
packages replaced the normal 'head' command that works on files,
with one that works on URLs. Has anyone encountered this, or can
anyone determine if my surmise about one of the perl packages is
correct? Thanks.
This is a common gotcha on Os X. For some reason which I forget,
but which I think was due to backwards compatibility with earlier
versions of MacOs, the standard file system is not case sensitive:
HEAD and head are considered equivalent.
In the Perl distribution there is a script called "HEAD" which
indeed does fetch the header of an HTML file from the web. This
clashes with the standard Unix "head" command.
There is a standard workaround, but just renaming the HEAD script
solves things without (ISTR) breaking too much else.
