No such requirememt.

I expect it is in a non-default library tree. From 'Writing R Extensions'

     Note: R CMD check and R CMD build run R with --vanilla, so none of the
     user's startup files are read. If you need R_LIBS set (to find
     packages in a non-standard library) you will need to set it in the
     environment.
