On startup, Pd-Extended 0.43.4 reports that it is unable to load several libraries. PureData's site explains that getting errors like these means X11 is not installed, see here.

However, X11 IS installed on my MBP, and works fine when using it to remote into my Raspberry Pi, for example.

Has anyone experienced this issue?

here's a screen shot

I have the impression that these might be deprecated...
