A couple of other people have said it's a failure of Module::ScanDeps
to correctly identify all the required modules.. Some of which are
attempted to be loaded via a string-eval..

It makes sense, I suppose, since the name of the module it attempts to
load is generated procedurally.. but is a pain.
Manually adding all the DateTime::TimeZone::* files (and while one is
at it, the TZ::Locale::* files) did indeed fix the problem.

However, this seems like a wider problem with using PAR files..

How do you detect undetected runtime requirements?
Just install *every* requirement to a private INC, then PAR it in it's entirety?

Thanks for the help,
