[R] Problem with utils package

[juansantomero7432 at yahoo.com]

Dear List,
I am having the following problem. 
I just installed a new version of R on Ubuntu Trust LTS, following instruction on CRAN website, but the associated utils package which got installed appears only as version 3.0.2.
On an older version of R (3.1.2) which I am running on a Windows machine, the associated utils package is version 3.1.2.
So, my question is why was such an outdated utils package installed as part of a brand new R??? Using this older version of utils is causing me all sorts of problems, and because it is part of the base package, I don't seem to be able to install a newer version of utils. Any help would be greatly appreciated!
many thanks,Juan
