I think the tests assume there's a perl present even when the PERL
prereq isn't present already. E.g.:
nul_to_q () {
"$PERL_PATH" -pe 'y/\000/Q/'
}
So in practice the PERL prereq just means "NO_PERL wasn't set", or
in other words, "commands that use perl work". Maybe something
like the following would help?
