I updated my computer to Yosemite and now when I open pd-extended it gives me this:
/Applications/Pd-extended.app/Contents/Resources/Scripts/../extra/pdp/pdp.pd_darwin: dlopen(/Applications/Pd-extended.app/Contents/Resources/Scripts/../extra/pdp/pdp.pd_darwin, 10): Library not loaded: /usr/X11/lib/libX11.6.dylib
Referenced from: /Applications/Pd-extended.app/Contents/Resources/extra/pdp/pdp.pd_darwin
Reason: image not found
pdp: can't load library

I don't know how to fix this problem so that I can use it again. Help please!!!!
