kmail - OpenPGP plugin not specified - where to get it?

Hi all, when I receive PGP encrypted Emails from Windose users (Eudora, PGP) kmail (from kde3.1b2) pops up an error saying "OpenPGP plugin not specified". Where do I get this plugin? I did read somewhere to check the German government sponsored Aegypten project, but there I did not see a plugin to download. Now I have to save the message, start kgpg and decrypt it, it would be so much nicer to have kmail handling the decryption for me. Thanks, Matt
