sim offers a daily snapshot on it's project page. I modified the sim-0.9.1.ebuild to leech and compile this snapshot. I used it as sim-0.9.2.ebuild on my system but this name should be changed. Because the snapshot has a different md5sum every day something should be done with the digest, but that's my first ebuild and I don't know how to do it.

daily snapshot is WAY too much maintenance for us to keep up with.
