Plugin dependency issues with Avro codec on Logstash 5.0.0 alpha4

[vtipparam]

Hello,

I am forced to uptake 5.0.0 alpha4 for Kafka input plugin with Kafka 0.10 support. Now I am running into a dependency problem with Avro codec. Apparently it has issues with logstash-core. See below for the plugin install output. Please help.

Thanks,
Venkat

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
