the existance of the local installation does mean you did something out of the ordinary from a distribution point of view. you had a local installation with version 1.4.8 and the distribution version is 1.4.9 and your local installation was not correctly set up to restrict itself to the local files. The distribution version in /usr/bin should work just fine.
