Ah, this must be OSX installer magic.  I've run into it with  
frameworks, but this is the first application "upgrade" that I've had  
to deal with.

When the installer "upgrades" an installation, it removes the older  
version as best it can.  It uses the application ID to say whether an  
application is the same, in this case "org.osgeo.grass6".

I have configured the installers to allow "downgrading", so that is  
probably why installing 6.3 over 6.4 leaves 6.4 alone.  (I wasn't  
quite sure what this really meant.)

I can look into options to disable the upgrade magic, or I may have to  
do what I do for framework upgrades, and temporarily move the old  
version before installing the new version (bleh).  Or change the ID on  
each version.
