RPM cannot just replace a directory with a symlink.

One can add a %pretrans to rename the directory and
accomplish the tranform between directory <-> symlink.

That has been described many times and many places,
most recently as a question & answer (with an explicit
example test case for regression testing) at
	http://launchpad.net/rpm
