I can say two things:
1. Here's the source for most of the PAR-related logic that Catalyst
uses:
http://search.cpan.org/src/SRI/Catalyst-5.61/lib/Module/Install/Catalyst.pm
It doens't do anything with this environment variable.
2. My hard drive has started to make a noise that concerns me. I hope
it's just cold. (Could be. It's -5F as I prepare to walk to work!)
