Failed to build qt5-qtlocation: command execution failed

[alanterra (Alan Harper)]

I am trying to install QGIS3 and py311-pyqt5 on macOS Sequoia 15.0.1, and both fail when installing qt5-qtlocation. I started by deleting all traces of macports, then reinstalling macports, then, 1 by 1, installing my ports. The two listed here fail to install. I did

sudo port clean qt5-qtlocation
sudo port install qt5-qtlocation

I am attaching the log file from this attempt.

The log shows the error is:

:info:build deps/boost/1.65.1/include/boost/mpl/aux_/integral_wrapper.hpp:73:31: error: integer value -1 is outside the valid range of values [0, 3] for the enumeration type 'udt_builtin_mixture_enum' [-Wenum-constexpr-conversion]
