This is probably due to a different default locale between your two
installations, and not a bug in the coreutils.

Again, if locales are the culprit, then this is probably due to sort not
sorting the file in a manner where uniq sees identical lines next to one
another (perhaps because the locale ignores case or punctuation).  This is
a FAQ:
http://www.gnu.org/software/coreutils/faq/coreutils-faq.html#Sort-does-not-sort-in-normal-order_0021

Try again with LC_ALL=C set in your environment, to see the difference.
