But it is present, as you can check using env | grep DYLD. We cannot
read your shell and environment startup files for you – you need to find
it on your own.

Those people are wrong, it certainly isn't, and that the loader filters
those environment variables on setuid and setgid binaries is a good
thing (because it would otherweise open up a huge security hole).

Because its startup files do not set the variable.
