regex - How do I use a new-line replacement in a BSD sed?

Question

Greetings, how do I perform the following in BSD sed?

sed 's/ /
/g'

From the man-page it states that will be treated literally within a replacement string, how do I avoid this behavior? Is there an alternate?

I'm using Mac OS Snow Leopard, I may install fink to get GNU sed.

In a shell, you can do:

    sed 's/ /
/g'

hitting the enter key after the backslash to insert a newline.
