Log Message:
* Move info file entrise to PLIST.

* Remove patch-ac which patched the Makefile to install the example config
  file into the examples directory and replace with an appropriate
  INSTALL_MAKE_FLAGS setting.

* Remove SUBST_FILES setting and replace with a patch.  This will make
  merges with future updates easier.

* Fix the location of the example configuration file to match where it's
  actually installed.  Now, the file will actually be copied over during
  POST-INSTALL.
