In general I try and remove the older one - you can remove specific
versions of duplicates by specifying their full name including the
version. i.e.

   yum remove brscan4-0.4.3-1

but you need to pay particular attention to any warnings or examine
which other packages yum might want to remove.  There will be a reason
why two versions ended up being installed (usually there's a bug or an
install got interrupted half way through). It might be easier to remove
the more recent one first, then do another update.  Bottom line is,
don't use '-y' or automatically press 'y' when doing this!
