Well, you do a 'yum search', of course. And then there you will find something called 'googlecl'. So you do
# yum install googlecl
Now, you could just write a blog post within a text file and post to the blog by doing;
% blogger post --tags "GoogleCl, Fedora" --src /path/to/post/file --title "your post title"
That's it! :)
