Comment (by robe):

 Myon has run into a similar issue, so I'm changing this to a blocker

 From IRC 2019-10-06 logs

 15:56:39        Myon:   anyone around who can explain how scriptdir() in
 regress/run_test.pl is supposed to work?
 15:57:04        Myon:   that broke Debian's (hackish) way of running the
 regression tests on the installed packages
 15:57:43        Myon:   things work at build time, but when the regression
 tests are told to run on the installed packages, they fail
 15:57:49        Myon:   errors like

 16:00:29        robe2:  Myon that's interesting I get similar error too --
 I thought it was just something on my local setup as bots aren't
 experiencing that - https://trac.osgeo.org/postgis/ticket/4515

 16:01:02        Myon:   there is code to make it use the location from
 pg_config, but the glue around it is weird

 $version and $version ne $libver ) {
