maybe ubuntu/debian changed their favorite ordering of compiler flags again?

what are you using grok for?

[jskarpe]

I was planning on using it for Logstash

[jordansissel]

Ahha, well you're in luck! You don't need to compile grok anymore; logstash ships with it internally with each release! :)

[jjasghar]

I'm attempting to build grok from source like @Yuav was. I'm trying to learn grok on another machine; and durring compile i get something that looks extremely similar. Any advice?
