Errors trying to build#4

I tried to grab the project and build it two ways, neither of which worked. This isn't super pressing (I don't want to submit a pull request when I can't confirm it builds), but I thought I should at least let you know I'm having issues. :) When I try to clone and build the project, it goes horribly wrong. ``` % git clone https://github.com/erickt/rust-serialization-benchmarks Cloning into 'rust-serialization-benchmarks'... remote: Counting objects: 216, done. remote: Compressing objects: 100% (28/28), done. remote: Total 216 (delta 14), reused 0 (delta 0), pack-reused 188 Receiving objects: 100% (216/216), 147.25 KiB | 191.00 KiB/s, done.

The backtrace says it is in `main`, so not super helpful there, sorry (I haven't gotten line numbers on my mac for a while). ``` % git clone https://github.com/erickt/rust-serialization-benchmarks Cloning into 'rust-serialization-benchmarks'... remote: Counting objects: 216, done. remote: Compressing objects: 100% (28/28), done. remote: Total 216 (delta 14), reused 0 (delta 0), pack-reused 188 Receiving objects: 100% (216/216), 147.25 KiB | 0 bytes/s, done.
