Almost every langs have a CPAN alike. They just copied it.

CTAN for TeX, CCAN for C, forgot the ruby name, LISP has it even with a cpantesters alike testers grid, PHP split it into PECL for binary extensions (higher quality) and PEAR, which struggles. emacs lisp, node.js, ocaml, ...

go uses git only for their distributed module system, which is a nice and simple idea, (github as default) but also appeared in common lisp before.

I think the question was less "What other languages have module repositories like CPAN" and more "Does anyone know of other module ecosystems that are running projects like this to get people involved?"
