But he still must make sure that "R CMD check" has  'pkgname'
in its R_LIBS :

Instead of 'set R_LIBS=....'  {which seems to indicate you use a csh-alike}
	setenv R_LIBS=.............
	R CMD check ....

or --- typically better, since the R_LIBS setting remains "local" ---

       env R_LIBS=...........  R CMD check <mypkg

       (all in one line)
