Current versions of CPAN can be configured to request a sudo password at
the install step, while running the rest with normal permissions.

IIRC (I use cpanp, and I haven't had to set this up in a while):

In the CPAN shell should set it up for you.  Depending on what order
you've done things in, some temp folders may have been created with
root-only access at this point, which you might need to change.  (That is:
If they were created by a 'sudo' run, they'll have root-only access. 
Otherwise they'll have access for your user.)

You also don't need to go to the shell, and 'cpan' should be installed as
a stand-alone script:

> cpan i Module::Name

But all of that is basically just making things a bit less verbose and
noisy.  (And the one safety of not running tests as root.  Note that some
module tests will _fail_ if run as root...)
