It is installed, but only for 32-bit and you are trying to load it in 64-bit R.

Use 32-bit R or if you want to use XML in 64-bit R, you have to compile it for 64-bit. AFAICS XML currently doesn't pass checks on any platform, so there are no binaries and you have to compile it from sources. If you want both 32-bit and 64-bit you'll have to use --merge-multiarch INSTALL option or use the two-step process described in the Mac FAQ.
