Well, this is my first attempt with Cherokee and I thought server!listen was a valid configuration key. However, the latest GIT checkout gave:

$ /opt/cherokee/sbin/cherokee -C ./cherokee.conf 
ERROR: Server parser: Unknown key "listen"
Couldn't read the config file: ./cherokee.conf

This has been reported already and is said to be fixed with changeset 2766, so why is this still happening?

Update: As an observing reader pointed out, the correct key is named server!bind!1!interface now. The changelog is rather quiet about this, but searching in the commits reveals that this change has been made last year already, though the documentation still mentions server!listen.
