I did a search also, just last weekend. I did come up with a reference to it being newly built in the 'unstable' repo, but when I did a search for emelfm2 deb files that's all I came up with. http://ftp-master.debian.org/new/emelfm2_0.7.4-1.html
I don't use it a lot, though I did download the source file and installed gcc but there were errors when I tried to make or make install or one of those, and not being a coder and not wanting to make it a weekend project I gave up. I'm just going to keep an eye on the testing repo and hope it makes it's way into that repo shortly.
Looking more closely at the page above, I see this line:
Build-Depends: debhelper (>=8), libgtk2.0-dev, libmagic-dev
So I may check to see if I have those or what versions are available for us in testing and try again. If you come up with anything feel free to share the news!
