thanks a lot

Acording to datasheet from atmel.com atmega128 have two variants one is
some kind of bga
and the second is TQFP64_14. Then in my opinion it can be safely changed
from TQFP64 to TQFP64_14 in /usr/share/gEDA/sym/micro/ATmega128-3.sym.
Because it's quite a bit confusing when you add symbol from geda library
and it doesn't work.
