Try

file = open(url, "rb")

instead of

file = open(url)

and

f = File.open('openssl-1.0.0c.tar.gz', 'wb')

instead of

f = File.open('openssl-1.0.0c.tar.gz', 'w')

. You're downloading a binary file, and Ruby will do bad things to
newlines in it if you don't pass the "b" for binary.
Additionally you should have a look at the block form of #open.
