help pages for CRS duplicated?

I encountered the following. My quick and simple search of past 
emails in R-sig-geo didn't find any previous discussion.

 search()

".GlobalEnv"        "package:rmacq"     "package:rgdal"
   "package:maptools"  "package:sp"
   "package:foreign"   "package:stats"     "package:graphics"
  "package:grDevices" "package:utils"     "package:datasets"
   "package:methods"   "Autoloads"         "package:base"

 find('CRS')

[1] "package:sp"

 ?CRS

Help on topic 'CRS' was found in the following packages:

   Package               Library
   rgdal                 /Library/Frameworks/R.framework/Resources/library
   sp                    /Library/Frameworks/R.framework/Resources/library



Followed by a request to identify which one to view.

Thanks

(In case anyone wonders, rmacq is a local personal package.)
