CPAN modules on Leopard

I've just bought a new Mac with Leopard preinstalled, and am getting 
it set up, including my Perl programs.  (I've actually skipped Tiger 
entirely; the old computer is on Panther.)  They depend on a number 
of CPAN modules, and I am having trouble getting the modules 
installed.  I've installed the Developer Tools, updated CPAN, and it 
sort of installed Term::ProgressBar (the first module one I tried). 
However, it's giving me some complaints about being unable to find 
Class/MethodMaker.pm both when I try installs in CPAN and when I try 
to run my test programs.  Below is an excerpt.  Does anyone have any 
guidance?  I'm not finding anything useful on the Web.  Thanks your 
your help.
