Thanks for letting me know such an issue. But it should not be a problem you need to face to:

First, you do not need to generate any codes in order to use slim or to run the tests.
Everything is ready in its git repo. 😆

Second, your protobuf is a little bit old. I tried several version and find out that only proto v1.0.0 has this issue. Upgrading to at least v1.1.0 should fix this issue(We have been using v1.2.0). To upgrade:

cd $GOPATH/github.com/golang/protobuf
git checkout v1.2.0
go install ./proto ./protoc-gen-go/

Then make gen && make test should pass.

I am gonna add some comments to elaborate on what env/lib slim relies on ASAP. 😆
