R help - Jul 2013 - cluster package - Installation problems

Group - I'm having problems with the 'cluster' package. Installation
appears successful but attempts to load it with either library() or 
require() result in the error message

Error in library(cluster) : there is no package called ?cluster?

All that appears to be installed is cluster.dll in the 
library/cluster/libs/x64 folder. Several reinstallation attempts haven't 
helped. I'm using R-3.0.1 under windows 7. Any help is appreciated.

Regards

David

Restart your R (and close other R processes) and try again, probably the 
dll was locked by an(other) R process when you tried to update.
