basically
.PHONY: describe
means that make doesn't look for a file named `describe' first. Try
touch describe; make describe
in any port with and without adding `.PHONY: describe' to the Makefile.
You can get some more info with
make -d m describe
I know that the search path in ports make is usually very small, so it is
unlikely that you run into it. OTOH, go in any category directory and do
mkdir -p describe; make describe
with and without adding `.PHONY: describe' to bsd.port.subdir.mk.
IMHO declaring targets as PHONY makes sense, even though these are border
cases in the ports tree. I'll add that to PR 64233, since `extract patch
configure build install package' are really meant to be stand-alone targets.
