You will have to do it over and over, for each version and won't
benefit from the ELGIS update.
I would not recommend that.

Just remove the version you had compiled from source.
Instead of deleting the files under /usr/local, just move them
somewhere so that you can move them back in case something go wrong
(but, again, it is unlikely to get worse than now)
