I frequently encounter this same problem when I run my tests. From what I've read, the problem harks back to older versions of Pod::Man. It didn't require Pod::Simple, and it didn't require Encode. The =encoding UTF-8 didn't come around until grantm put it into Pod::Simple---and that was around 2012; whereas perl v5.14.0 came out in May of 2011. Reinstall Pod::Man, Pod::Simple, and Encode. Then reinstall DateTime::Locale.
