The full output is quite long so I have pasted it here: http://pastebin.com/raw.php?i=JiJeH4ij

I’m new to Perl modules and thusly, completely lost. What’s going on here?

UPDATE:

$ perl --version

This is perl, v5.8.8 built for i486-linux-gnu-thread-multi

$ lsb_release -a
No LSB modules are available.

    This is likely your problem.

    Package seems to come without Makefile.PL.
  (The test -f "/home/bensley/.cpan/build/DateTime-0.72/Makefile.PL" returned false.)
  Writing one on our own (setting NAME to DateTime)

    Your copy of the CPAN client is so out of date it does not recognize the “new” (by which I mean 10 years old) Build.PL module build and install mechanism. CPAN instead wrote its own installer and tried to do the installation anyway. This will work for many Perl modules, but it probably missed some subtlety required by DateTime.

    Upgrade the CPAN client, you can do it with the CPAN client, and then try again.
