Hi @timsan, There's a few threads on this topic and it is being addressed. This is the most recent:
It seems aviationweather.gov has changed things. Anyone have an ETA?
I hacked my libmateweather.so.1.6.9 file with a binary editor and it works great. A real developer wouldn't care for this, of course. 
EDIT: For the record, the aviationweather.gov lead web developer has jumped into the picture and is still working on things. Cross your fingers it may be fixed by this Wed and with no changes to all the Ubuntu and other Linux distros it affects.
