 Looks like the package need a fix similar to #61464

Comment:

 This has nothing to do with #61464. That was about undefined symbols,
 which is a consequence of a libtool bug that appears on macOS 11 and
 later. This, on the other hand, involves implicit declaration of
 functions, which is now an error in Xcode 12 and needs to be fixed by
 declaring the functions before using them.
