I'm guessing (again) I should read it as "syntax-wise they are defined by the

I'm not aware of any haskell ebuilds that set ':=' only in DEPEND but not
propagate it to RDEPEND.
Crude hack
gentoo/metadata/md5-cache $ for f in */*; do if egrep -q '^DEPEND=.*:=' $f;
then if ! egrep -q '^RDEPEND=.*:=' $f; then echo $f; fi; fi; done
reports a few unrelated packages.
