go - package's type cannot be used as the vendored package's type

Question

I'm trying to use this Golang Yelp API package. In some of its structs, it uses types defined in guregu's null package.

I want to declare a struct defined in the Yelp API package, where some of its fields have null.Float as a value (i.e. this struct, which im trying to use). So in my program, I import both the Yelp API package and guregu's null package and try to declare the struct, with ip.Lat and ip.Lat being float64s. (null.FloatFrom definition):

 33         locationOptions := yelp.LocationOptions{
 34                 ip.Zip,
 35                 &yelp.CoordinateOptions{
 36                         Latitude: null.FloatFrom(ip.Lat),
 37                         Longitude: null.FloatFrom(ip.Lon),
 38                 },
 39         }

But when I run the program, it tells me:

./cli.go:36: cannot use "github.com/guregu/null".FloatFrom(ip.Lat) (type
"github.com/guregu/null".Float) as type "github.com/JustinBeckwith/go-
yelp/yelp/vendor/github.com/guregu/null".Float in field value

I tried 2 things:

1) I did not import the null package, which caused Go to complain about null being undefined. 2) I also tried importing the vendored package directly, which caused Go to tell me use of vendored package not allowed.

Any Ideas on how to fix this?
