Nope. Not GPL-licensed.
MIT License is GPL-compatible.
Cue the BSD vs MIT license flame wars over whether the BSD license is free enough or whether one needs the sublicense right grant in the MIT license to achieve full freedom ;-)

I consider the MIT license to be freer than the GPL. Nonetheless, you can fork it and slap the GPL license on it if that lets you sleep at night.
