Summary: packman upgrade issue

Initial Comment:
When you upgrade a package using packman the installer doesn't 
remove the old version before installing the new version. The end 
result is that old files might interfere with the correct operation of 
the upgraded package.

I ran into this with an upgrade from PyObjC 1.0 to PyObjC 1.1. 
Some extension modules have moved between those two releases. 
When upgrading using PackMan the old extension modules still 
exists, and cause problems when you try to use the package.

Three possible solutions:

1) Remove the existing package directory before installing the
    upgrade

2) Add pre/post install/upgrade scripts

3) Use a real package database
