We're talking about two completely different domains that both happen to use the filesystem for storage. Ruby gems are not packages in the same sense that Firefox is a package. It's a different concept, and although I agree that Pacman could do an acceptable job of managing Ruby gems insofar as both systems bundle files for installation, it is not possible to map the two systems completely. They are built for different purposes, and have different semantics. > Yes, gem is easy to use, so is pacman.

To some extent, yes. You end up with a lowest-common-denominator situation.

Based on that paragraph, I'd be surprised if you had undertaken any serious development in Ruby. Many Rails developers work on Macs (not to mention other flavours of Linux), and Rubygems and Bundler are cross-platform tools. Relying on Pacman for Ruby development would render a project pointlessly platform-dependent. Paul
