error trying to install belchertown. my weewx install was using setup.py. I 
downloaded the belchertown 1.2 tar.gz into my home/david/Downloads folder. 
I ran the sudo wee-extension command and get "File 
"/home/weewx/bin/weecfg/extension.py", line 134, in install_extension 
weecfg.extension.InstallError: Extension 
'/home/david/Downloads/weewx-belchertown.1.2.tar.gz' not found.
can't find what i did wrong. Should i extract the tar.gz file first? move 
it to another folder to start install?
