My mistake.  I just installed a new Perl from the CPAN shell, and it
uses a prefix of /usr/local - but vendors who supply Perl in /usr/bin
change the default prefix to /usr, I just verified this on RedHat Linux.

So while I was wrong to blame Joseph, the general point remains that
filename conflicts may occur just as well on case-insensitive
filesystems.  It's better if LWP avoids such conflicts but it
isn't unique if it doesn't.
