@envygeeks it looks like this needs a rebase but is good to go after that.

Never mind. I don't think that's going to be an issue. Just going to wait for Travis to tell me it's green and then I'll merge.

Isn't the error on Appveyor related?

Looks that way. I'm going to hold off on this then until that's fixed. I know Windows isn't officially supported but I don't see a reason to merge something that we know is going to regress that platform.

just confirmed.. I was unable to run script/default-site with this branch on my Windows machine..

Code looks good but the windows build needs fixing.

@envygeeks The issue here is that Windows doesn't parse the shebang #!/usr/bin/env ruby like Unix does.. so to run a ruby executable on Windows, the program creates two helper files in the bin/ directory in the %PATH% (in this case, RUBY_VERSION/bin/bundler.bat and RUBY_VERSION/bin/bundler)

But in the context of this PR, you can achieve the same by passing "ruby" to the utility function

- process, output = Jekyll::Utils::Exec.run(exe, "install")
+ process, output = Jekyll::Utils::Exec.run("ruby", exe, "install")

[envygeeks]

I'll get it fixed.
