A couple of comments..

* uninstall.m doesn't take cell arrays and so you can have the problem 
of circular dependencies on removal... Given the install code, in 
shouldn't be too hard to get the same functionality there.
* I see no reason that you can't install over an existing package, as in 
this case it is an upgrade. I'd first remove the existing version and 
replace with the new version after the dependencies have been checked..
