Better, just put Depends: R (>0.62) in DESCRIPTION, or just forget
about R pre-1.0.0.  

Package akima has the same problem.

.First.lib is not relevant to help.  Have you loaded the package or not?
Something like

> help(interp, package="akima", lib.loc="/ext/R/library")
> help(package="akima", lib.loc="/ext/R/library") 

works whether it is loaded or not.  The semantics of this got changed
around 0.99.0 to try to ensure that the help came from loaded libraries.
So you can do

library(akima, lib.loc="/ext/R/library")
?interp
help(interp, package="akima")

and you will get the help from the loaded library even if there is
a version in the standard library.
