The Evolution plugin for Mail Notification doesn't work/exist (LP#355209)

In mail-notification 5.4 in Ubuntu Jaunty (9.04), the following files are installed to /usr/lib/evolution/2.24/plugins/ instead of /usr/lib/evolution/2.26/plugins/:
liborg-jylefort-mail-notification.so
org-jylefort-mail-notification.eplug

A simple workaround:
1. Copy or link the files to the correct directory:
   

   sudo ln -s /usr/lib/evolution/2.24/plugins/org-jylefort-mail-notification.eplug /usr/lib/evolution/2.26/plugins/
   sudo ln -s /usr/lib/evolution/2.24/plugins/liborg-jylefort-mail-notification.so /usr/lib/evolution/2.26/plugins/

2. Restart evolution and go to Edit -> Plugins -> Jean-Yves Lefort's Mail Notification. Check the box.
3. Right-click on the Mail-Notification icon -> Properties. Add your evolution e-mailbox.
