Sorry, it contradicts the facts.

It is. See:

$ cd /usr/pkgsrc/archivers/unzip/
$ make
=> Required installed package digest>=20010302: digest-20060826 found
audit-packages: not found
===> Skipping vulnerability checks.

Stop.
make: stopped in /usr/pkgsrc/archivers/unzip
$ stat /usr/pkgsrc/distfiles/unzip-5.52/unzip552.tar.gz >/dev/null && echo ok
ok

$ stat /usr/pkgsrc/distfiles | cut -d ' ' -f1-6

With fresh pkgsrc tree.

Thus, you can't reuse read-only DISTDIR.
