update your macport... hopefully it should be ok :)

sudo prot selfupdate :)

Updating the ports tree has no effect.

The error is in /opt/local/include/libunwind.h It tries to include <__libunwind_config.h>, which doesn't exist.

The actual location of the config file relative to the header is "libunwind/config.h". So changing the line

#include <__libunwind_config.h>

to

#include "libunwind/config.h"

solves the problem. Someone should update the port accordingly.

Sounds like a duplicate of #49781, except that you said updating the ports tree has no effect.
