A := only makes sense for a dependency that is present both at build

time and at runtime. Currently, the only place you should be seeing

a := is on a spec that is listed in both DEPEND and RDEPEND.



Conceptually, the := applies to "the spec that is in both DEPEND and

RDEPEND". But with the current syntax, there's no such thing as "the

spec that is in both". There are two specs, which happen to be

identical as strings, one in DEPEND and one in RDEPEND, and there's no

way for the two to be associated.
