That's possible. I initially downloaded several Perl modules and 
installed them manually, then ran into module dependency problems when 
trying to install others and was then shown how to use the MCAN auto 
install method (THAT was a godsend to a new user!).  Perhaps the use of 
"sudo" for some installs and not others created an ownership problem?

Yes. Many of the duplicates are in the /.cpan/build/ directories.

Because I am new and inexperienced, I'm almost willing to just clear 
everything out of the /Library/Perl/5.8.1/ directory and start over. 
(That would still leave Perl itself installed on my machine, wouldn't 
it?) That probably sounds drastic but, to me, it almost sounds simpler 
in terms of making sure everything is properly installed.

I _really_ appreciate the help I'm getting from list members but some 
of the suggestions are difficult for me to understand and follow given 
my limited understanding of the system. I don't want to ask too many 
questions and become a pest but I also don't want to "smile and nod" 
when I don't really get it.

Thanks!
