No idea what the problem is there, but it looks like a setup.py/pip/git/etc intersection issue. It wasn't easy figuring out how to get that to work a couple of years ago, and it's most likely borken in the meanwhile. My advice would be to check out the head/master and build from the source: "python setup.py build".
It's not an ubuntu/linux problem, I was running shrapnel just today on 12.04.
[I'd like to promise to fix it soon but I'm insanely busy for the next few weeks]

I got this exact error from pip when installing another package, and it turned out to be a bug with my old pip (1.0) in handling tarballs containing symlinks. You can upgrade your pip, or extract the tarball and run setup.py yourself.
