That's probably related to SIP. See the following post from Jonathan
Perkin for more info:
In particular, Jonathan writes:
SIP does not disable DYLD_LIBRARY_PATH, it only ignores it for
binaries *that are protected by SIP*. Nothing built by pkgsrc is
protected by SIP.
You might get around your problem by using a shell from pkgsrc. For
example, here's a comparison of /bin/sh and /opt/pkg/bin/mksh using
$ DYLD_LIBRARY_PATH=foo /bin/sh -c 'echo $DYLD_LIBRARY_PATH'
$ DYLD_LIBRARY_PATH=foo /opt/pkg/bin/mksh -c 'echo $DYLD_LIBRARY_PATH'
However, as Jonathan wrote, SIP is actually ignoring DYLD_LIBRARY_PATH
for binaries that are protected by SIP, so even if you use a shell from
pkgsrc (that is not protected by SIP) but then use a protected binary
from the macOS system such as /usr/bin/env (like you may have been
trying to use in your test), DYLD_LIBRARY_PATH will still be ignored:
$ DYLD_LIBRARY_PATH=foo /opt/pkg/bin/mksh -c '/usr/bin/env' | fgrep DYLD
$ MY_VAR=foo /opt/pkg/bin/mksh -c '/usr/bin/env' | fgrep MY_VAR
