You can extract the prefix from the installed package by grepping for @cwd in +CONTENTS. Similarly you can extract the list of installed files by doing grep -v ^@ +CONTENTS. For each package that has our origin (or a previous origin as looked up in the MOVED file), do the following: if the installed prefix =3D=3D $PREFIX and one or more of the installed files matches a file in pkg-plist (checked using e.g. comm(1)), then we are going to conflict and we should not install. I can't immediately think of how to implement the installed plist extraction without using a temporary file, but it should be possible with some thought.
