[R] Building package: What does this message about rcompgen imply?

[Prof Brian Ripley]

We don't have any of the basic details the posting guide asks for!

If this is R 2.5.0, rcompgen is a recommended package and ought to be 
installed.  If it is not, then .check_Rd_refs cannot cross-check 
references against all the standard and recommended packages, and that 
looks like the cause of the error.

If it is an earler version of R, the advice in the posting guide to update 
applies.  CRAN will be checking on 2.5.0 and later.
