2. message appears

Expected behavior
A clear and concise description of what you expected to happen.

I've used Redshift since the project started with Slackware, and since that time I have never seen this message before, in fact I've never had any messages, it's always run perfectly.

So I'm assuming with a newer updated system, newer gtk, X, libs, dependencies, etc., is the reason for this message, and Redshift needs to be updated.

Error output/logs/screenshots

Software versions (please complete the following information):

  Built from source

Is there anyway I can fix this issue?

THANKS
