just install assumes that gopath is configured in your zsh file.

[KyleVasulka]

just install fails if gopath is not set to
export GOPATH="$HOME/go"

Also during install it puts it as bin in the goopath so the otto command does not work.
renaming the binary to otto and putting it in a folder called bin in the gopath fixed this.

but this should be a bit more automated plz
