[SOLVED] Dev Hugo not building due to afero.NewReadOnlyFs errors

I tried to build Hugo tonight on OS X after pulling the latest from spf13/hugo and it failed in hugo/commands on the afero package. Go get -v fails with the same error:

$ cd github.com/spf13/hugo
$ go get -v

And go get -v -u fails with a slightly different error:

macpro:hugo mdhender$ go get -v -u

Looks like a recent commit on spf13/aero is the cause:
