That's not what happened:

- there's a lot of UI code, so it's not a mere distribution for Mac, not even sure it qualifies as a port at this point

- also, the authors page states Letov as the first author

It's in fact a fork. And unless the original author is ok with that, you shouldn't advertise your fork under the original name.
