You can send a pull request on Github at https://github.com/keplerproject/luarocks or just send a patch here at the mailing list, whatever is more convenient to you (on our end, the pull request is preferred of course since it's less work to integrate.) > 2 - Related to problem number 2. How to deal with the differences in library > search conventions in different OSs? LR should already be handling that, that's odd... take a look at external_deps_patterns (in `src/luarocks/cfg.lua`). On Windows, there's both "?.dll" and "lib?.dll" there... is the library file called libpq.lib, by any chance?
