Comment:

 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 maintainer and are several major versions out of date.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.
