R help - Oct 2004 - Question about version argument of require() and library()

As far as I know, the following should work. Can anybody tell me 
if/where I am going wrong?

 > packageDescription("KEGG", field="Version")
[1] "1.6.4"
 > require(KEGG, version="1.6.4")
Loading required package: KEGG
[1] FALSE
Warning message:
There is no package called 'KEGG', version 1.6.4 in: library(package, 
character.only = TRUE, logical = TRUE, warn.conflicts = warn.conflicts,

TIA,

Jim

Did you install this package with --with-package-versions?  The `version'
argument picks up a particular versioned installed, not an ordinary
install of the right version.

We have rather little documentation on versioned installs.
