Possible error when building "gstreamer"

[Dave Horsfall]

Whatever "gstreamer" is...  Anyway, can anyone translate this gobbledygook 
into plain English, so that I can file a bug report if necessary?

Result from my weekly "port upgrade outdated":

     --->  Building gstreamer1-gst-plugins-base
     Error: Failed to build gstreamer1-gst-plugins-base: command execution failed
     Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_gnome_gstreamer1-gst-plugins-base/gstreamer1-gst-plugins-base/main.log for details.
     Error: Follow https://guide.macports.org/#project.tickets to report a bug.

When I found my way to that stupidly long file name, I got what appears to
be this salient entry in the log:

So, what now?  This weekly stuff normally works for me.
