The R posting guide asked you to ask the maintainer, but as this is a 
MacOS X issue, on the R-sig-mac list.  It's not appropriate for R-help 
because of

'Questions likely to prompt discussion unintelligible to non-programmers 
should go to to R-devel.'  (R posting guide.)

Also R-sig-geo would be appropriate for support questions for this 
package.

You need a later version of the Xcode tools. 
RSiteSearch("-macosx_version_min") got me there on the first hit.
