I have upgraded my system from Ubuntu 11.10 to 12.04, and a script I wrote chokes on execution looking for the module 'use DateTime::Format::DateManip;'.

dpich@dpich-M6400:~/Documents/Copyright$ perl ./script.pl 
Can't locate DateTime/Format/DateManip.pm in @INC (@INC contains: /etc
+/perl /usr/local/lib/perl/5.14.2

+pt.pl line 14.

So just install the module. But....
