Didn't notice your mention of the module version until I verified that 3.00 is the version where that line number made sense. The line number for that line is off by two in version 3.02. Strangely enough the two line difference is the addition of
croak("Could not load my own date parsing: $@")
I'd grab the newer by a year version of the module and see if you get different results, though perhaps that might be getting the error message.
(Looking at why code in __DATA__ might fail ... do you have module Time::Local installed on your system?)
