Is Codec => gzip_lines supported on 5.1.2?

[Allie_Yang (Allie Yang Yang)]

I am trying to read a local gzipped file with below, but i can't even install gzip. Error also below. Is it supported yet?

file {
path => "/Users/alliey/Desktop/log_file/generic20161017.log.gz"
start_position => "beginning"
type => "json"
codec => gzip_lines{ charset => "UTF-8" }
 }

error:
