Sometimes the README file tells you how to upgrade.  Sometimes the
installation script can tell there's an older version and do what's right
or inform you what to do.  Otherwise I uninstall the old version first,
unless there is a reason not to.

I'd remove the old RPM first unless there is a reason not to.

I remove the older version first and install the RPM via -i, unless there
is a reason not to.

Because I don't like to keep track of all these problems, I just stick
with RPMs and try to avoid compiling things myself.  That doesn't always
happen, unfortunately :(
