FWIW, on F7 I get:

[1] "‘text’"

[1] "“text”"
options(useFancyQuotes = FALSE)

[1] "\"text\""
The differing behavior between OS X and FC4 is perhaps due to the
available character sets and the locales, presuming that they may not be
the same. See the Details section of ?sQuote.
I might also point out that FC4 has been EOL for some time. It would be
prudent to consider updating to a more recent version. FC6 and F7 are
the currently maintained releases, with F8 due to be released on
November 8.
