Bug #103537 for DateTime: Unable to upgrade DateTime via 'cpanm'

I am having difficulty upgrading DateTime via 'cpanm' on the machine described in the perl_V attachment. Let me say at the outset that the version of DateTime currently installed is in a directory tree governed by local::lib, i.e., it's in a location dictated by job requirements rather than by my own use of 'cpanm', 'cpan', etc. The currently installed versions of relevant packages, as observed via 'perldoc -m <module>', are: DateTime: 0.72 DateTime::Locale: 0.45 DateTime::TimeZone: 1.42 The full output of 'cpanm', the build logs, etc., are attached. Here I quote relevant extracts. ##### $ cpanm DateTime --> Working on DateTime Fetching http://www.cpan.org/authors/id/D/DR/DROLSKY/DateTime-1.18.tar.gz ... OK Configuring DateTime-1.18 ...
