I'm not convinced that's true, as the depth and quality of rubygems are inferior to the depth and quality of eggs available in python. Find me e.g. a "gem install scipy" equivalent for Ruby.

However - "easy_uninstall scipy" REALLY needs to work!

I believe the parent was referring to the rubygems system, not the quality of the gems themselves.

My point precisely. I was referring to the package management system being better, not necessarily the packages available.

Can you explain more? Is there better native packaging (deb/rpm) etc support?

Rubygems is a separate system from deb/rpm, but works roughly the same way. Typically it doesn't do binary packaging the way they do it, though, and if native (non-ruby) code is required it is compiled during the install.
