[ryandesign (Ryan Carsten Schmidt)]

This is not Yosemite-specific; it's because in readline 6.3 certain symbols were renamed. For example, CPPFunction was renamed to rl_completion_func_t.

Thanks ryandesign! But, the change in question just handled the symbol renaming; what about the completion_matches() issue?

[ryandesign (Ryan Carsten Schmidt)]

That's just a warning, not an error. Does it cause a problem for you?

Replying to ryandesign@…:

Ah, right you are. No, no problem. Thanks again!
