On newer versions of macOS, DYLD_* environment variables are no longer passed down to subshells. This merely means that you need to set DYLD_LIBRARY_PATH at the right time, in other words right as you're running svnversion, and not in some top-level script that will eventually after calling various sub scripts run svnversion.

I have not looked at your build system, but it fails for the reason I stated.

It is crashing. The operating system crash logs (attached to the MacPorts ticket) were what alerted me to the problem.

Sure, here's one of the logs from our build system:

https://build.macports.org/builders/ports-10.14_x86_64-builder/builds/44459/steps/install-port/logs/stdio

The relevant part in the log is where it says:

(subversion/svnversion/svnversion . 2> /dev/null || \
         svnversion . 2> /dev/null || \
         echo "unknown"; \
        ) > /opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_devel_subversion/subversion/work/destroot/opt/local/include/subversion-1/svn-revision.txt
/bin/sh: line 1: 61814 Abort trap: 6 subversion/svnversion/svnversion . 2> /dev/null

Distribution tarball.
