make install will always overwrite whatever stuff is there and using the 
same name.  It also leaves all the no-longer-used garbage or 
differently-named stuff.

Therefore, when upgrading MythTV (even revision to revision within a 
same-versioned branch--and especially when going to a 
differently-versioned branch), it's always recommended that people who 
are not using package management do a make uninstall--using the *old* 
version of the source that was used to install the old version of MythTV 
(i.e. the one that knows about all the file names used by the old 
version).  You can't use the new version to do a make uninstall and 
expect it to properly clean up.

If you do anything different, cleaning up the leftovers is your own 
problem to deal with (or ignore--it shouldn't cause any real problems, 
unless you leave around old, incompatible plugins, if you prefer).
