Scheme Mode: preventing evaluation of *.pkg when opening?

[Nicholas Papadonis]

I downloaded the mit-scheme source and encounter the following behavior when 
opening a file named “runtime.pkg”.

<— snip —>
“The local variables list in runtime.pkg contains values that may not be safe 
(*)”
“Do you want to apply it?”
“Please type y, n, or ! or C-v to scroll”

Then I answer “n” and the same screen is presented again.

Finally the mode line indicates “Scheme Gambit/A”
<— snip —>

Does anyone know what is causing this behavior vs just simply loading the 
buffer?  How do I disable this behavior?

I’m not sure why Emacs is trying to evaluate a buffer when I have not 
instructed it to do so.

Thank you,
Nick
