Mac OS X: Cannot install HTML::Timeline, don't know what it is (was Re: timelines from GEDCOM files_

I've been testing HTML::Timeline on my Linux box where I installed it  
as an RPM (after making a few tweaks and running cpan2rpm  on it).

On my Mac OS X box, however, I'm getting this error when I try to  
install HTML::Timeline:

[pdurbin@macbook ~]$ sudo -H cpan -i HTML::Timeline
Password:
CPAN: Storable loaded ok
Going to read /var/root/.cpan/Metadata
   Database was generated on Mon, 11 Aug 2008 22:02:56 GMT
Warning: Cannot install HTML::Timeline, don't know what it is.
Try the command

     i /HTML::Timeline/

to find objects with matching identifiers.
[pdurbin@macbook ~]$

I assume this is because the .cpan/Metadata database generated on Mon,  
11 Aug 2008 is too old to include HTML::Timeline, which is so new.

Can anyone please suggest how to update the .cpan/Metadata database so  
I can pull down a new module?

Can anyone please suggest an alternative way of installing Perl  
modules on Mac OS X so that I can remove packages like I can with  
RPMs. I'm aware of fink and macports, but I would need to submit the  
Perl module as a package spec to the maintainers of those systems, I  
suppose.

Thanks in advance,

Phil
