[Rd] Rd.sty not found

[Lori Shepherd]

I'm trying to build and check a new package. But keep getting the
warning: 

* checking PDF version of manual ... WARNING
LaTeX errors when creating PDF version.
This typically indicates Rd problems.


When I go into the package.Rcheck directory, 
package-manual.pdf is created.  
however if I do a pdflatex on package.tex I get the following: 


This is pdfTeX, Version 3.1415926-2.4-1.40.13 (TeX Live 2012)
 restricted \write18 enabled.

How do I fix this? I have never had this problem when building or
checking packages before? 


Also of note: I notice that the pacakge-Ex.R and package-Ex.Rout run
without error  but the package-Ex.pdf is empty and there is no
associated package-Ex.tex to look at.
