I am trying to use Perl the first time on my system which is Ubuntu 12.04. I have Perl v.5.14.2 installed.
I looked up how to install Perl modules, so I started as follows:
$ perl -MCPAN -e shell
The wizard started configuring the environment as can be seen here: http://pastebin.com/5hn8vkb5
Though, it stopped in the middle with the following error message:
...

Can't locate local/lib.pm in @INC (@INC contains:

/etc/perl

/usr/local/share/perl/5.14.2
/usr/lib/perl5
/usr/share/perl5
/usr/lib/perl/5.14
/usr/share/perl/5.14
/usr/local/lib/site_perl
/home/john/Desktop)
at /usr/share/perl/5.14/CPAN/FirstTime.pm line 1300.
What can I do to setup the Perl environment correctly on my Ubuntu installation?
After interrupting the wizard and restarting it again, there is no error message anymore. How can I start the wizard again so I can choose here:
What approach do you want? (Choose 'local::lib', 'sudo' or 'manual') [local::lib]

Perl interpreter is compiled with a specific @INC default value. To find out this value, run env -i perl -V command ( env -i ignores the PERL5LIB environmental variable - see #2) and in the output you will see something like this: $ env -i perl -V ... @INC: /usr/lib/perl5/site_perl/5.18.
To install Perl modules using CPAN, you need to use the cpan command-line utility. You can either run cpan with arguments from the command-line interface, for example, to install a module (e.g Geo::IP) use the -i flag as shown.
Solution: If you get a Perl error message like "Can't locate Foo.pm in @INC", this message means that the Perl module you're trying to include (like the module named Foo ) can't be found in Perl's include path, which is represented by the variable named @INC .
Several New OS's force (like Redhat 7) force to check presence of local::lib in the perl version, actually its a good thing this enables to users to use CPAN and add,experiment and enjoy new modules to be used with the perl without waiting for sitewide installation (like a root user). By default local::lib looks for $HOME/perl5 dir where the user's local or downloaded modules are located. If you see this problem then you have to do following
