Source: postgis Version: 3.1.3+dfsg-1 Dear Maintainers,
your package build-depends on autoconf2.13, which is obsolete and orphaned in Debian (see #977321). Please investigate migrating away from autoconf2.13, possibly to autoconf 2.69 or newer (package name "autoconf"). A quick test rebuild with autoconf2.13 dropped from Build-Depends appears to work. I could not find an upstream commit since 2016 that hinted at an autoconf upgrade, so maybe it has happened even earlier. Please give it a try :-) Thanks, Chris
