There is no plugin folder in my aperture support folder to place the FExp plugin

I downloaded FExp Plugin1 for Aperture, but couldnt find the correct spot to copy to, as the aperture folder in App support library does not have a plugin folder. I copied it in the Aperture folder with all the other .plist files but it doesn't work for me. Help please! (I did successfully download facebook uploader for aperture and it works fine though)
