why you remove - s.add_dependency "vagrant", ">= 0.9" ? - now we have trouble if we install veewee
... block in replace_gem': vagrant is not part of the bundle. Add it to Gemfile. (Gem::LoadError) ...

It's probably the .rvmrc aliases for vagrant.
Do you use the veewee vbox commands or the vagrant basebox commands?

The idea is that veewee doesn't require vagrant gem - if can create the vm without vagrant being installed.
I figured if @mitchellh will no more support the vagrant gems but only the installer it doesn't make sense to keep the dependency.
@mitchellh any thoughts on this?

thanks, so we must install vagrant separately.
Can "bundle install --without vagrant" be an alternative?
