gambas3 is one such example. In creating the package it uses itself to 
create some modules, but if it is already installed, it uses those 
binaries to create them instead, leaving you with a package linked to 
stuff from a previous install that will no longer be available. You have 
to do a removepkg before creating a new one.
On that subject, is it worth adding a test for previous version in the 
slackbuild, and should the build just stop if one exists, or should it 
be allowed to remove the previous existing installed version?
