Correct those pesky errors.

I noticed autoreconf runs libtoolize, among other things. You probably had libtools for quite some time.

When you don't have them, as I did, and you run autoreconf, it will suggest you add this RANLIB thing, which is pointing you the wrong direction (but does get the build to succeed). If all is well, these two lines aren't needed. I have no strong feelings about them....
