Running tests fails with "vagrant" error message

[Matt Connolly]

Hi, when I run `rake` to run tests in sshkit, I get an error message that just says "vagrant", see:

I'm not sure how to debug this one, I've never used vagrant before today. Any tips?

Using:

ruby: ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-darwin13.0.0]

rake: rake, version 10.1.1
vagrant: Vagrant 1.4.2
os: Darwin MattbookPro.local 13.0.2 Darwin Kernel Version 13.0.2: Sun Sep 29 19:38:57 PDT 2013; root:xnu-2422.75.4~1/RELEASE_X86_64 x86_64


Thanks
Matt
