those libs have been removed. You need to update your preferences by going to:

Edit > Preferences > reset to default

Well,

I am having some issues, but I think they are mostly due to my setup or
something... I'm running on 10.8.2 Mac OS X, bt.

I have been running 0.42.5 because I didn't want to risk it. So I waited
for a more stable version of pd-extended to start working hard on it. I
already had issues on the betas for 0.43.3 so I wasn't really in hurry...

so now, thing is pretty simple. First of all, I'm not getting any audio
output. Even when it starts, pd-extended  gives me an audio i/o error that
quickly disappears.

I'm also getting this message:

memento: can't load library
pixeltango: can't load library
rradical: can't load library
toxy: can't load library
flib: can't load library
flatspace: can't load library
pidip: can't load library


and it really can't load the libs :(

I feel pretty lame but... help?
