That is probably your problem. caret is at 4.15 and earth is now at
2.3-2. caret 3.45 was released on 2008-10-17 and many changes have
been made to both packages since then.

No, not at all true. I build it on OS X and R-Forge checks it every
night. Please don't extrapolate, especially if you haven't sent a
reproducible example.
