HTC used to have a copy of the Linux binary, but they changed their developers portal and now I can't find that one anymore, either. The only other pre-compiled version I've been able to find is here (link originated from this thread on droidforums.net, which also has a link to a pre-compiled OSX binary).
I checked with
readelf on my Linux VM and it looks like it's a 64-bit binary, so I've also uploaded a 32-bit version to my Dropbox public folder, and it can be downloaded here. This is the binary I use on my machine, which I believe I got from the aforementioned HTC site that's now missing.
Aside from that, you can compile Android from source to get it...but that's kind of a terrible solution for a single small binary file.
