The log contains 21 attempts to install this port. The first dozen or so attempts failed because:

:info:build Undefined symbols for architecture x86_64:
:info:build   "half::_toFloat", referenced from:
:info:build       gst_openexr_dec_handle_frame(_GstVideoDecoder*, _GstVideoCodecFrame*) in libgstopenexr_la-gstopenexrdec.o
:info:build ld: symbol(s) not found for architecture x86_64

The remaining attempts failed because you originally had gsed installed but then uninstalled it, leading to:

:info:build ../../libtool: line 1323: /opt/local/bin/gsed: No such file or directory

I think half::_toFloat is, or used to be, part of one of gstreamer1-gst-plugins-bad's dependencies, openexr. Maybe openexr was updated to a new version that no longer exports that symbol and this old version of gstreamer1-gst-plugins-bad is not compatible with it. Maybe updating gstreamer1-gst-plugins-bad, and the rest of the gstreamer1 ports, to the latest version would fix the problem. The ports do not currently have a maintainer and are several major versions out of date. Perhaps someone can volunteer to figure out what is necessary to do the update.

On the other hand, we did have a ​successful build of gstreamer1-gst-plugins-bad on the macOS Sonoma x86_64 buildbot worker in October and openexr was last updated in August. The buildbot build log has already expired but I just tried a build on my Monterey x86_64 system and it succeeded. I will see if I can find any relevant differences between your log and mine.

Unfortunately I don't see an explanation when I compare our logs.

Maybe there have been other changes in MacPorts that caused a momentary problem back in September when you first tried which have been resolved since then. Could you try sudo port clean gstreamer1-gst-plugins-bad and sudo port sync and then try building it again? Let's see if the same error about half::_toFloat occurs then.
