Prepend error was added in Thrift 0.9.3, and is present in the current codebase:
If it isn't being found in your local library, you need to update your local (or vendored) version of Thrift.
Remember, your thrift generator binary (in
/usr/local/bin/thrift) can be a different version than the package you have in your
$GOPATH. Always make sure you update the two together.
