I have never quite understood why language developers never thought providing their platforms a little bit more like Linux developers do with distributions, i.e. besides providing libraries only, also provide package managers, dependency resolvers, test & rate the packages, dump orphaned packages, and so on.

I encountered this problem especially while learning Lisp. After you learn the basics of the language, and decide you want to do something productive with it, you find out that in order to do basic tasks, which other platforms nowadays include in their standard libraries, wading through and evaluating all the half-finished libraries all by yourself, because the community wont do it, will in the long run take more time than you needed to deal with the language itself.
