My project used gin, and in gin, you can use built in 'encoding/json' or 'jsoniter',
my porject use 'encoding/json',so in $GOPATH/src,I don't have jsoniter,my gin works good
when i use 'godep save ' my project,shows info:
godep: Package (github.com/json-iterator/go) not found

I think there are a lot like this, because gin used govendor, when i entered gin' s source direcotry,use govender list,there are lots of missing, but i build success

When i 'godep save' may i exclude some,like in my case,exclude jsoniter?

in https://github.com/gin-gonic/gin/blob/master/tools.go
in https://github.com/gin-gonic/gin/blob/master/Makefile
when you make tools, gin will install github.com/campoy/embedmd;
in my project use go get install gin , will not install embedmd
but in my project i just "go get -u github.com/gin-gonic/gin", would not install
github.com/campoy/embedmd

when in my project i use godep save:
godep: Package (github.com/campoy/embedmd) not found
