[R-SIG-Mac] Mac installation of R not liking lattice

[Waichler, Scott R]

The following code runs fine on Linux, but not on my Mac.  The error
message is given below, after the levelplot() call.  I was able to run
lattice functions previously on the Mac without any problems.  I don't
know what has changed.  I searched R-help and found a similar problem
that wasn't answered.  My Mac is running Xcode 2.5, in case that is
relevant.
