Comment (by cswingle):

 I just spun up a Xenial virtual server with the ubuntugis-unstable PPA and
 couldn't replicate the issue.  I think the problem may be that at one time
 I built a custom GDAL which is still in `/usr/local/gis` and has a linker
 entry in `/etc/ld.so.conf.d`.  The system GDAL is `GDAL 2.2.1, released
 2017/06/23`, but PostGIS is seeing the custom-built `GDAL 1.11.3, released
 2015/09/16`.  I no longer need the custom GDAL since the packaged versions
 have long since surpassed it, but I'm leery of blowing it away for fear of
 it breaking PostGIS on a production system.
