Hi, I built the latest (yesterday) master of Julia and am struggling to get Pk3 up and running. I’m on Win10 and it can’t find a program to run `sh` files:

```julia

(v0.7) pkg> develop Tokenize

I assume there’s something in cygin that’ll do the job, any tips on where it is/ how to add it to my path?  
Thanks

Looks like something is expecting busybox, I’m not sure what though. We’re not using busy in Pkg3 at all (that I’m aware of).

Please open an issue on the Pkg.jl repo.

I opened a PR that should fix it.
