The _LIBCPP_ENABLE_CXX03_FUNCTION macro that allowed re-enabling the now-deprecated C++03 implementation of std::function has been removed. Users who need to use std::function should switch to C++11 and above.

Regarding comment2 by kencu is the problem in MacPorts configuration of the botan1 (corrected by the botan1 port provider some day in the future)
or do the user of the port (i.e. me) have to try to figure out to do something on the basis of the Xcode 15 release notes to be able to install the port?
(qt4-creator-mac is the port I need but it depends on botan1)?
