Just wanted to add, that if a dependency is needed for runtime but not
for building, then it can be listed in the depends inside the actual
package() function.

In that case, makepkg *still* does the right thing, because it doesn't
install a non-build-time dependency...

(This is usually relevant in split packages, in which case the
makedepends includes all the individual package() depends -- but it
could be used to separate runtime-only depends. If it actually was
important to pander to this very limited and not-well-justified use-case.)
