Brian,
   Thank you for the effort to explain the fallback directory. I'm sorry I
may not have been clear enough on my thought process. I read the fallback
conversations on the list and saw the hplato commit that added this to the
external /bin files, so I knew what was happening... but I have yet to
figure out which module was causing the issue. I tried deleting every
module that WeatherNOAA depended on but there was still an error (blank
forecast).

   I thought that I was on the right path a few different times by changing
code, updating the weatherNOAA module, changing {zone} to {state}, etc,
etc... but I recognized that I may need to take a step back and begin
again, since I have have drawn some false conclusions about what fixed it -
especially when I discovered that removing fallback had a positive effect.
I offered my code as a talking point, but realized it wasn't the "right"
fix.

   My question should be closer to something like this: Does anyone have it
working with the fallback directory in the library list? I deleted LWP::*
and restarted MH without any success, and moved on to Tie::IxHash, then
some Text module that I forgot the specifics on. I suppose I could continue
deleting modules and testing, but I was growing weary of the process.

   Perhaps a better question is this: Who's running hplato/master with
internet_weather successfully? What did you modify?
