Perl upgrade @INC help



I am in the process of upgrading Perl on a very old box via:

# perl -MCPAN -e shell

....and have run into something I need advice on.

I need to know before I answer the following question whether the
modules I've installed under 5.005 as stated in the first sentence will
be installed if I hit enter to the 'List of earlier versions to
include...' question if I leave it as [none]. If not, do I just type
5.005? How can I ensure that it at least attempts to install the older
modules? Does [none] mean don't do any?

-- what I see on screen --

Looking for a previously installed perl5.005 or later...
Using /usr/local/bin/perl.

In order to ease the process of upgrading, this version of perl
can be configured to use modules built and installed with earlier
versions of perl that were installed under /usr/local. Specify here
the list of earlier versions that this version of perl should check.
If Configure detected no earlier versions of perl installed under
/usr/local, then the list will be empty. Answer 'none' to tell perl
to not search earlier versions.

The default should almost always be sensible, so if you're not sure,
just accept the default.
List of earlier versions to include in @INC? [none]
