I don't think we should error if pkg-config was not found and --with-guile
was left to "auto". This is going to break the build of many of us
who work on systems that don't have that tool installed (I've just
noticed that on Windows). Intead, let's disable guile support
when that happens.

For the second error, I think we should apply the same principle.

Can you adjust that part, please?

Thank you,
