I write in Clojure and I take great pains to avoid introducing dependencies. Contrary to the popular mantra, I will sometimes implement functionality instead of using a library, when the functionality is simple, or when the intersection area with the application is large (e.g. the library doesn't bring as many benefits as just using a "black box"). I will work to reduce my dependencies, and I will also carefully check if a library isn't just simple "glue code" (for example, for underlying Java functionality).

This approach can be used with any language, it just needs to be pervasive in the culture.
