There are several reasons why you should do it anyway:
1) downloading over rsync will save you bandwidth. It adds up if you
push a module update to N machines. Also you are saving the CPAN
server's bandwidth, which is nice to the owners.
2) a local CPAN mirror works even if your outside internet connection
is down (with some caveats).
3) hard drives are extremely cheap, a few GB is a really small amount
of data these days.

Cool, but mirroring everything is definitely easier to setup and
maintain, in addition to the above reasons. No custom software, just
an rsync in the crontab and that's it.
Hope that helps...

Ah, but you asked about *installing* all of the modules - that's not the
best solution for the situation you're describing now.
All you need to do is download a local copy of your favorite CPAN
distribution site, and configure CPAN.pm to download from a file:// URL
that points to your local copy.
See <http://cpan.org/misc/cpan-faq.html#How_mirror_CPAN> for more on
creating a local CPAN mirror.

This would be an argument for having your own private CPAN mirror it
doesn't justify trying to install all modules.

Yes, but it doesn't *hurt* to have them around, and its nice to not
have to run to cpan to fetch and install another module every time you
need something new, which is fairly often when you're in a
learning/exploring binge, as I am right now!
To contrast CPAN with, say, a RedHat distribution - I always select
"custom" and then "all packages" because disk space is cheap (full
install of RH9 is 5GB) and time is expensive, so on the off chance
I'll need something obscure, why not have it ready for me to use?
To answer the original poster's question, there is a theoretical 'yes'
answer - install Bundle::Everything. However, this is completely
impractical, as half the modules on CPAN have some broken tests, and
even if you force installed Bundle::Everything, a great percentage of
modules have interactive installs, or will simply not work even when
forced.
What *would* be nice, besides auto-install everything, is something
like yum or red carpet, but for CPAN. A single command that will look
for, fetch, and install the newest versions of all modules you already
have installed.

From "perldoc CPAN.pm":
Programming Examples
This enables the programmer to do operations that combine functional-
ities that are available in the shell.
# install everything that is outdated on my disk:
perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
