Even though I've decided to use the cpan location, I think the decision
for the MacTeX installation is completely correct. The only thing I
would say is that I think the documentation should highlight the
potential conflict in the case of a pre-existing Perl/Tk install -
especially since /usr/bin takes precedence by default (but really
whichever way it works).

What I still don't understand, though, is the behaviour of the
installer in /Library/Perl. Why does the installer not update an older
installation? And why does it leave a bunch of "temporary" files in
/Library/Perl? Finally, given that it does/does not do these things,
why does the install appear to succeed without offering the user any
explanation or warning?

I don't mean to sound overly critical. I'd really like to know why it
was designed this way.
