+This really look like a general PERL problem, but google search returns no relative result of undfined method 'distribution' at FireTime.pm at all. Answer on where to look for answer is appreciated too. Using perl 5.18 on NETBSD 6.1

+CPAN.pm requires configuration, but most of it can be done automatically.

+
+Warning: You do not have write permission for Perl library directories.
+
+To install modules, you need to configure a local Perl library directory or
+escalate your privileges. CPAN can help you by bootstrapping the local::lib
+module or by configuring itself to use 'sudo' (if available). You may also
+resolve this problem manually if you need to customize your setup.
+
+What approach do you want? (Choose 'local::lib', 'sudo' or 'manual')
+ [local::lib] local::lib
+
+Autoconfigured everything but 'urllist'.
+
+Now you need to choose your CPAN mirror sites. You can let me
+pick mirrors for you, you can select them from a list or you
+can enter them by hand.
+
+Would you like me to automatically choose some CPAN mirror
+sites for you? (This means connecting to the Internet) [yes] yes
