[Ifeffit] Did anyone upgraded to SeaLion aka Mavericks (MacOS 10.9)

Dear all, one question to the early adopter. Did anyone tried ifeffit already on Mavericks? Is there any known issue beside the X11/Quartz issue? I have it installed ifeffit on MoutainLion with the know trick to "emulate" the old X11 (was on the mailing list).
