Having a script.pl how can I automatically download from CPAN all required modules and install and update as required? Something like "emerge -uDNav world" for the perl?

Doesn't matter I've found it
cat *.pl | grep "^use " | tr ';' ' ' | while read a b c; do echo $b; done | sort -iu | while read a; do cpan $a; done
In the CPAN shell:
o conf prerequisites_policy follow
o conf build_requires_install_policy yes
o conf commit
It's not working:
# perl backup.pl
Can't locate Crypt/OpenSSL/PBKDF2.pm in @INC
Posting the result of cpan <module_name> will be helpful (we don't know what backup.pl contains).
If need to automate the download of the dependencies, you may need to configure the Internet connection:
o conf init connect_to_internet_ok
or
o conf init urllist
# cpan Crypt/OpenSSL/PBKDF2.pm
Going to read '/root/.cpan/Metadata'

Looks good

I believe that you need the OpenSSL headers and you need to install them manually. Use CPAN to install Perl modules, not OS packages.
Thank you, it was solved installing the SSL headers
sudo apt-get install libssl-dev
