Sounds like you are using your own preferences file. If you move/remove that, then it'll use the built-in prefs, and all the libs will be loaded.
rm ~/Library/Preferences/org.puredata.pd.plist
yep that was it. i thought that there was none, but there was an empty one.
thanks hans and i'll change the netpd-gui-extended and remove all " zexy/" so it should work with both pd's.
now if only the entry in a gop would work again. does it for you?
