Fixing Laforge cty.primitiveType errors

laforge_cty_error_fix.md

When running laforge, if you get the following error:

panic: gob: registering duplicate types for "github.com/zclconf/go-cty/cty.primitiveType": cty.primitiveType != cty.primitiveType

The following steps can be taken to fix it:

1. Edit $GOPATH/src/github.com/hashicorp/terraform/vendor/github.com/zclconf/go-cty/cty/types_to_register.go
2. Comment out the following import statements:

 "math/big"
 "github.com/zclconf/go-cty/cty/set"

3. Change func init() to look like this:

 func init() {
   InternalTypesToRegister = []interface{}{
 //    primitiveType{},
 //    typeList{},
 //    typeMap{},
 //    typeObject{},
 //    typeSet{},
 //    setRules{},
 //    set.Set{},
 //    typeTuple{},
 //    big.Float{},
 //    capsuleType{},
     []interface{}(nil),
     map[string]interface{}(nil),
 45   }

4. Rebuild laforge using go build github.com/gen0cide/laforge/cmd/laforge
