Is this an issue for a Ruby installation process (warning: assignment discards qualifiers from pointer target type)?

Hi,

I'm on RedHat linux and installing Ruby but do get several warnings
(see below). Is this OK?

It's just a warning. Depending on the gcc options you use you get more or fewer warnings. Don't worry about it.
