Many thanks for your input. I had not considered the location of the code. I had gone only by what the repository had done. That may be a good thing to consider. My repository put the files in/usr/avr//usr/bin//usr/include/
The types of files that it put in those locations fit. That is the same file location/type that came from Atmel also. ??
Any time you download executable files, or even source code to build them, you are taking a bit of a chance. It is best if you stick to reputable suppliers. That link above is to the Atmel website, where I downloaded this from.
