I think the problem might be because you are using cp -R instead of cp
-dR.
The /lib directory likely contains both files and links (hard or soft).
[I'm on a Windows PC right now so I can't check :-(]. If you just use cp
-R then you will possibly be duplicating the files.
Eg if in the source you have:
File a (say 100kB)
A link to a called b (only takes a few bytes)
Then doing cp -R will give you:
File a (100kB)
File b (100kB)
I suggest you do an ls -ial to check the status of both directories to
check whether this happened.
